STILLEN is proud to announce the release of our KIA Stinger GT 3.3L V6 Twin Turbo Hi-Flow Air Intake.

STILLEN Hi-Flow Intake Kit – Oil Filter

STILLEN Hi-Flow Intake Kit – Dry Filter

402883DF 2018 Kia Stinger GT Intake

After many different prototype configurations STILLEN combined our multiple decades of experience with metal fabrication and poly-urethane manufacturing to produce a hi-flow air intake. We utilizes both processes as well as the factory ducting to produce an air intake capable of providing an additional 25 horsepower and 31 lb./ft. of torque.

Testing began by removing the factory air intake and thoroughly measuring and inspecting the intake tract, factory couplers, turbine housings, and filter surface area.  After measuring these key areas our engineering and fabrication team set to work in producing a pair of 3” mandrel bent intake tubes that provide a perfectly smooth airflow path from the air filters in to the turbine housings.

402883DF 2018 Kia Stinger GT Intake

By increasing the surface area of the filter by more than 50% and cleaning up the air flow with less drastic mandrel bent tubing we are able to control the air flow leading into the turbos and improve the efficiency of the intake tract and the turbos ability to draw air.

402883DF 2018 Kia Stinger GT Intake

To complete the air intake a set of poly-urethane shields were created which block off the hot air from the engine bay and prevent this heated air from entering the intake tract.

402883DF 2018 Kia Stinger GT Intake

Unsatisfied with simply developing a kit that fit and produced significant gains in power and torque, STILLEN held the release of the intake until it had been tested for more than 5,000 miles.  We worked with a local owner who drives their vehicle long distances and offered the use of the vehicle for durability and long term testing.  Here are his thoughts:

“I went on another trip to Phoenix, Sedona, Grand Canyon with the KIA Stinger. Stock I would get a 26 mpg (highest ever recorded stock). But on this trip, I logged the best 32.1 mpg at 90mph I did not get a pic of that, but I did get one of 31.9 mpg at 80 mph with the intake and tune that’s a 6mpg improvement! (long range driving). And when I filled it with gas, I got 375 mi usually it’s around 300-330 mi depends on my driving habits…. this was done on sport mode, that’s all I ever put it on.  P.S. I love the intakes especially when boost hits, if I’m next to someone and they hear the intakes most of the time they won’t pull up next to me (intimidating turbo sound, LOL) and it holds up good to the 107 heat in Arizona.”

STILLEN 2018 Kia Stinger GT

STILLEN is very excited to enter the KIA market with our poly-urethane body kit, cold air intake, and soon to be released cat-back exhaust.  For over 30 years STILLEN has been recognized as a leader in the high performance automotive industry and we are proud to bring our expertise and American Made manufacturing to new communities.  Look for more products from STILLEN soon!

Infiniti breathed some forced induction life into the Q50 Sport and Red Sport models with the inclusion of its all new, twin turbocharged VR30DDTT V6 engine. Conservatively rated from the factory with 300 horsepower (in the Sport) and 400 horsepower (in the Red Sport), these new “Q’s” make decent power off the showroom floor. However, like any turbocharged engine, reducing air flow restrictions allow the turbochargers to spool up more quickly while efficiently generating boost pressure. This translates into improved response, greater incremental gains and oftentimes, more peak power.

Unlike any other intake manufacturer, STILLEN’s longstanding relationship with Nissan helped to facilitate a genuine Nissan factory CONSULT diagnostics computer. Monitoring data channels that most in the aftermarket cannot, STILLEN engineers tested more than 20 different intake designs, evaluating numerous variables and noting the effects on specifics such as fuel trim, velocity and temperature, to name just a few. While the sheer number of prototypes might seem like overkill, the data collected enabled STILLEN to optimize the intake design for output and presentation.

Own a 2015+ Subaru WRX?

Then you might want to keep the following WRX performance enhancing tip to yourself:

The STILLEN 2015-2018 Subaru WRX cold air intake adds 30 HP and 32 lb-ft of torque at the wheels…no tuning required.  

Sound good? It should – the STILLEN Subaru WRX intake makes more power than any other intake that’s compatible with stock tuning.

2015-2016 Subaru WRX Intake

The 2015-2018 Subaru WRX intake makes loads of power – all with no tuning required.

These results are dyno-proven, running on California 91 octane fuel.

Does this make the STILLEN intake among the most cost effective power upgrades for the WRX?


In any case, may we suggest:

  1. You quietly acquire your very own STILLEN Subaru WRX cold air intake
  2. Secretly bolt it on by the light of the moon
  3. Volunteer to drive friends, family or significant other for morning coffee
  4. Deliver a caffeine-free rush to them on the way to the beanery

We won’t say a word.

However, pardon a bit of humblebrag about the development process.


STILLEN Subaru WRX Intake – A Success Story

STILLEN expertise in extracting major power gains without upsetting factory ECU settings is legendary.  Years of engineering intercoolers, turbo upgrades, exhausts and intakes comes in handy when analyzing the design of the stock intake on a vehicle like the WRX.

The STILLEN 2015-2018 Subaru WRX intake was designed to optimize airflow and give the MAF sensor the most accurate reading possible.

The dyno results speak for themselves with a factory-like AFR curve and massive gains across the power band:


Stillen 2015 Subaru WRX Intake 1v5 Dyno Results

Stillen 2015 Subaru WRX Intake 1v4 Dyno Results


All testing was done with stock tuning.  That’s important, because it gives you options:

  1. Today you can add significant power without investing in tuning software.
  2. Tomorrow you run it with tuning, whether custom or stage 1 & 2 tuning from Cobb.

No matter your resources or needs, the 2015-2018 Subaru WRX intake is there for you – tuning or no tuning.


Design Details:

When STILLEN Engineers were developing the WRX Intake they were already aware of the issues of other intake kits on the market. The fluctuating AFR readings made it clear that there needed to be adjustments made for MAF Sensor to get proper readings to the ECU and keep everything safe while still making more power. For this we looked at the design of the factory intake and MAF Sensor placement to see how the stock setup was communicating accurate information.


The Best Choice

So let’s take a look at the STILLEN Subaru WRX intake’s resume so far:  Powerful?  Check.  Cost-effective?  Check.  Versatile?  Check.  Dependable?  Yes sir.  And here’s why:

You may have read that running an aftermarket intake on a stock tuned WRX is unsafe.  When intakes were first being designed for the WRX, some manufacturers overlooked crucial details.

AFR’s were not closely monitored or data logged and the misinformation may have scared off the WRX community a bit.

Let’s set the record straight: here at STILLEN we’ve logged over 30,000 miles of operation with our cold air intake on engines with no tuning.

Zero check engine lights.

Zero issues.

Thirty some horsepower.

So here’s the best kept secret tip of the day:

Whether it’s the first or the final performance hop up for your 2015-2016 WRX, the STILLEN cold air intake might just be the best.

The STILLEN 2015-2018 Subaru WRX intake is currently CARB pending but we expect to have the intake fully smog legal in the near future.

Generation 3 STILLEN Cold Air Intake for Infiniti G37

Why Performance Air Intakes Are Better Than Stock Air Intakes:

When designing a vehicle the factory engineers are constantly dealing with compromises. Engineers will build the best vehicle imaginable. Then another set of engineers come in and make sure that vehicle will work for 99.9% of all people. From the young, aggressive, enthusiastic teenager to the middle-aged businessman and the little old lady using the car as a mode of transport. Once the car has been toned down enough for “everyone” to enjoy the accountants come in. Their job is simply to cut costs. Is the door handle necessary? Does the car really need a windshield? We joke, obviously, but the general job is to reduce costs as much as possible. In many cases their reducing the cost of the car without actually reducing the part, working with vendors to streamline their shipping processes, making adjustments to their manufacturing plants so they run more efficiently. Now you may be asking yourself, “what does this have to do with a cold air intake?”

By the time the vehicle has gone through the various levels of engineering, there have been compromises made for various reasons. The end result is a vehicle that has been de-tuned, and softened up. In some cases this is good, in others such as vehicle performance this means the engine isn’t breathing as well as it could and the performance isn’t as optimal as it could be. This is where we come in. As automotive enthusiasts, we want to hear the air intake. We want to hear the engine breathing. We want to feel the additional power. All of this becomes the character of the vehicle. To accomplish this there are a few things we do differently.

  1. Most vehicles come with a flexible intake tubing that looks like accordion tubing. This tubing creates turbulence as the air passes through. The turbulence is created by the riffles inside of the airstream. The goal when developing a cold air intake is to achieve a laminar airflow through the intake piping.
  2. Additional benefits can come by way of a larger air filter. Factory air filters are generally referred to as “panel filters” as they are simple drop-in squares or rectangles. Most performance intakes take advantage of an oval, circular, or more three dimensionally shaped filter. This allows for a larger surface area thus allowing for better filtration, less restrictive airflow.
  3. In most cases the factory air intakes are undersized and can create a bit of restriction in the intake path. By going with a larger diameter tubing it allows for a larger volume of air to be available to the engine.
  4. Some companies such as Injen technologies will manipulate the airflow to increase the velocity of the air as it travels through the intake piping.
  5. Some companies like AEM performance intakes will include a supplemental computer which can be attached to the factory MAF sensor to alter the signal being sent to the factory ecu. AEM calls this their ETI intake system or electronically tuned intake systems.
  6. When reviewing a cold air intake, the name itself tells the story. The goal is to simply draw air from the coolest place possible. By relocating the vehicles air intake location outside of the engine bay you are getting fresher, cooler air.

STILLEN dry filter

Why It Works:

Unlike stock air intakes, the design of aftermarket air intakes promote improved air flow into your engine. This increases the amount of oxygen that can be used for combustion. In turn, having additional air in your engine allows it to be more efficient – both in terms of horsepower and fuel efficiency.

Air is just like anything else in this world. It is made up of molecules and all molecules expand and contract depending on the temperatures in the environment they’re in. As the temperature increases the air molecules grow larger. As the temperature decreases the air molecules shrink and therefore become more dense. By reducing the temperature of the air you are effectively making the air more dense and the same volume of air becomes more oxygen rich.

To get the lowest ambient air temperature possible you have to move the air intake location as far outside of the engine bay as you can. This is the reason we relocate the filters and intake pickups to the front bumpers or between the fender and chassis rails. The goal is always the same, move the intake port to the coolest area getting the most direct airflow as possible.

Types of Intakes Available:

Cold Air Intakes

There are two different types of cold air intakes. Traditionally and most obvious are the intakes that re-locate the air intake pickup to outside the engine bay. These usually require a bit more mechanical knowledge as often times you’ll need to remove body parts such as bumpers or windshield washer bottles.


The other type of cold air intake looks similar to a factory intake with a sealed air box. The primary difference is that the air box is generally larger and in most cases re-routes its air intake location to somewhere outside the engine bay. In some cases these sealed boxes can employ ram air scoops with air being directed from lower parts of the vehicle such as behind the front bumper on many full-size trucks.

Many people prefer the OE looks of this style of intake. You also get a large air filter, and a larger air box which allows for a larger air reservoir for the engine to pull from. In most cases, these systems are the easiest “cold air intakes” to install.


STILLEN Cold Air Intake Airbox for Nissan Titan is CARB Exempt (EO# D-436-14) and good for 15whp / 27wtq

Why We Like Them:

  • Offers the highest horsepower for basic applications
  • Prevents Ingestion of Hot Engine Bay Air
  • Sealed Airbox Design WILL DRAMATICALLY Outperforms an Open Intake In Traffic or Hot Days

Short Ram Intakes

These systems are identified by their short, single tube design with an open air filter at one end. If you are looking for an upgrade in throttle response, then this is the air intake for you. Another major difference between the short ram intake and cold air intake is that the short ram intake is generally louder. In most cases this type of air intake is the easiest modification you can make to your vehicle. It’s even easier than changing the oil or headlight bulbs on most vehicles.

Why We Like Them:

  • Offers a distinctive sound and improved throttle response
  • Simplicity

Make Sure Your New Air Intake is CARB EXEMPT:

It is important to know your states laws and regulations regarding performance parts on your vehicle. In most states as long as you don’t have any check engine lights your vehicle will be passed and you will receive your registration quickly and easily. However if you live in a state that follows the CARB regulations (California Air Resources Board) you will want to make sure that the cold air intake you are installing is legal for use and operation on the roads in your state – intakes that are permissible for use in California will feature a CARB EXEMPT Executive Order number, that exempts that part from emissions regulations. Currently there are only a few states that have adopted CARB regulations, but more states integrate these regulations every year.

If you purchase a CARB EXEMPTED intake, your kit WILL come with a decal which you will want to place somewhere inside your engine bay. We recommend sticking it next to your vehicles factory emissions decals generally located under the hood. Another easy to locate place is on the front core support directly above the radiator.

Dry Filters vs. Oiled Filters

For years the debate has raged on, dry filters are better than oiled filters, oiled filters have better filtration capabilities than dry filters. The factor of the matter is, both types of filters work very well. These days filter technology has come so far and is so good that it really comes down to user/owner preference.

Airaid oiled filter

Oiled filters will not damage your MAF sensor. K&N engineering is recognized as being the first company to employ oiled filters in their intake designs. They have been testing their oiled filters for decades and continue to test their filters and oils against the latest technology coming out from the OE’s. Every time they test their products they find that there is no damage being done to electronic components or engine internals caused by their oils. For more information on this visit the K&N website here: www.knfilters.com/maf/massair.htm

Dry filters do have the added benefit of not even being able to bring up the question about oiling issues or anything like that. As the filter is completely dry there is no way oil can get onto electrical components or into the engine. If you find yourself uneasy about the idea of using an oiled filter even after reading all of the information provided earlier, a dry filter is going to be your best option. Another side benefit is that a dry filter is typically easier to clean


STILLEN is the only major retailer who also designs and manufactures their own cold air intakes, and we make it all RIGHT HERE, in the USA at STILLEN HQ in Costa Mesa. Founded by Champion Racer Steve Millen, STILLEN has been manufacturing cold air intakes since the early 90’s, applying our championship-winning race engineering experience to our line of performance parts for street vehicles. After all, if we can build an 800HP race car, why wouldn’t we be the people to trust with your street car? STILLEN has been working with CARB to achieve exemption orders for many products since 1995. Not only do we carry all of the major manufacturers such as Injen, Airaid, Volant, K&N, AEM we also manufacture our own intake kits that are seen as the leaders in their segments, often delivering the most horsepower and torque to the wheels in their class.


A frequently asked question is, what will happen to my warranty after installing a cold air intake? Your factory warranty will not be affected by installing a non-factory intake. The dealership/manufacturer has to definitively prove that the modification made to the vehicle caused the issue your vehicle is experiencing. It is important to know your rights on this: www.consumer.ftc.gov/articles/0138-auto-warranties-routine-maintenance

When you’re ready to take your car or truck to the next level, give us a call at 1-866-250-5542 and our experts will be happy to help you. We offer a variety of air intake systems including Injen air intakes, K&N air intake systems, AFE intakes, AEM air intakes and STILLEN air intakes.

What are some other ways you are increasing the efficiency of your engine?

We’re proud to announce the release of our STILLEN Generation 3 Ultra Long Tube Intake for the G37 Coupe (Part # 402846). This same intake also fits the Q60 3.7 Coupe. Some said that it was impossible to make horsepower with an intake on the VQ37HR, and we were determined to prove otherwise. This intake is the testament of the level of commitment from our R&D department, who went through over 50 variations before finalizing the design. The air filters are placed outside of the engine bay directly behind the main grille and are protected by a urethane splash guard.

STILLEN Generation 3 Ultra Long Tube Intake for the G37 Coupe On Car

Dyno Sheet and Product Photos:

Here’s the product text from the STILLEN Website:

STILLEN was the first national tuner to introduce a high flow intake for the G37 Coupe. Our first short tube intake provided a small boost in power with a great sound. Economical and easily installed, this Generation 1 Short Tube Intake became instantly popular. Some months later we introduced our Generation 2 Long Tube Intake, featuring polished tubes, even better sound and a power gain over the Generation 1. Our continuing dedication to getting the maximum performance from each vehicle has lead to the introduction of our new Generation 3 Ultra Long Tube Intake for Infiniti G37. This intake has a radically new design that provides dramatically better power than any G37 intake on the market. Our R&D team went through over 50 variations before being satisfied that this system is the best that can be made for the G37 Coupe.The new Generation 3 Ultra Long Tube Intake places two large K&N filters in front of the radiator and directly behind the main grille. Strategic placement of the filters allow for optimum cold air flow and easy filter removal for cleaning. It features additional polished tubes that pass through the front core support, larger air filters than the Generation 2 unit, a urethane splash guard to help protect the filter and a system of varied diameter tubing and steps to maximize air velocity.The power result: A dyno-proven 18.5 horsepower gain at the wheels. This translates to an estimated 22 horsepower gain at the flywheel. No other intake for the G37 can match these power gains!Recommended installation requires removal of the front fascia clip (not absolutely necessary, but significantly aids in ease of installation) and slightly enlarging the holes through the front core support. Installation time is estimated at two hours for an experienced technician. No other part relocation or parts removal is required.


If you have any questions about the long tube intakes, please visit www.stillen.com or give us a call at 866-250-5542 and we will be happy to help you. We also offer a wide variety of parts including an Infiniti G37 big brake kit, exhaust systems, and superchargers.  If you live in the Orange County, CA area, we also offer installation at our performance shop.
