Good for 18.5WHP / 13WTQ Power Gain – CARB EXEMPT EO# D-436-22
Just announced… STILLEN cold air intakes for Nissan and Infiniti vehicles have been granted CARB EXEMPT EO#’s through 2014! For over 20 years, STILLEN has worked with the California Air Resources Board (CARB) to develop products that are compliant with OE standards of total vehicle integration and performance while still satisfying emission control regulations. With this long history in mind, STILLEN is proud to announce the cold air intakes for the Infiniti Q50 and Q60 have been granted CARB EXEMPT Executive Order numbers. These numbers mean that the part has been shown not to alter or modify the design or performance of the factory emissions control equipment. While a typical aftermarket intake will automatically fail visual inspection, intakes with a CARB EO# will not fail a visual inspection, allowing the car to still be emissions tested as usual. We are equally proud to announce year range extensions for the 2014 370Z , Maxima and more. For a full list of vehicle applications, please see below.
STILLEN was the first company to prove that a cold air intake on the VQ37 engine could actually make power and is still recognized as the leading cold air intake with the highly sought after Generation 3 long tube cold air intakes for the 370Z, G37 and Q60. It took 6 months of in-house R&D and testing and 56 different variations of prototype intake systems but it was all worth it and the end result was the leading cold air intake for the VQ37 equipped vehicles.
When it came time to manufacturing air intake systems for vehicles like the Altima, Maxima, Titan, Frontier, etc. STILLEN leaned on its vast experience in manufacturing high performance parts for NISSAN/INFINITI vehicles. On the Nissan Altima and Maxima applicationsSTILLEN is the only manufacturer of high performance intakes that incorporates a poly-urethane ducted air intake path leading fresh air from behind the factory grille directly into the air intake filter. Included in many of these kits is STILLEN’s unique velocity ring which increases the velocity of the air as it is drawn into the engine thus producing more power!
Note: The California Air Resources Board (CARB) is a division of the California state government and is widely recognized for having the most stringent emissions control regulations in the United States. Therefore, each of the 50 states recognizes its standards as the emissions standard for all performance parts. Each performance part that achieves CARB EXEMPT status is considered 50-state legal.
STILLEN CARB EXEMPT Cold Air Intakes (EO# D-436-21)
A few months back this menacing black SRT8 came through for a Magnuson Supercharger install. It was already boasting some heavy modifications like upgraded suspension, cat-back exhaust, carbon fiber front lip, hood and trunk.
Check out the lighting set up on this black beauty!
There are a few supercharger options available for the Dodge Challenger, including forced induction kits from Whipple and Edelbrock, but it seems like the Magnuson has been the favorite for the 6.1L Hemi as of late.
The Magnuson Supercharger is a CARB EXEMPT (EO# D-488-16) Hybrid Roots supercharger that is a 100% bolt-on system and is said to produce approximately 120 horsepower and 120 ft pounds of torque to the wheels.

Some may think that this is too much to ask for, but the truth is it is possible and the answer is simple: Get a new air intake kit for your car or truck. Air intakes not only make your engine more powerful, but they also make your engine more efficient. Plus, you get the added benefit of a better sound and improved performance!
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.
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.
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.
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.
Some companies such as Injen technologies will manipulate the airflow to increase the velocity of the air as it travels through the intake piping.
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.
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.
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.
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.
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
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.
Warranty
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
For over 25 years STILLEN has been recognized as a leader in Nissan/Infiniti tuning. With a history of setting “first time” milestones in the aftermarket for these great vehicles, STILLEN has established themselves as the company to follow when it comes to Nissan and Infiniti product development. STILLEN was the first company to develop the HICAS eliminator system for the 300ZX Z32 platform. When the Z33 350Z was introduced, STILLEN was once again the leader with the first forced induction solution, as well as the first to offer CARB legality, and AGAIN the first with a 3-year/36,000 mile engine warranty.
Well, STILLEN has done it again as Team STILLEN is proud to announce the CARB Exempt Status of the Nissan 370Z (Z34) G37 Supercharger Kit. STILLEN has not only been the first company to achieve CARB Exemption of a forced induction solution on the VQ37, we have also been the first company to achieve such an accomplishment while tuning through Nissan’s sophisticated ECU with larger injectors. This is a major accomplishment for Team STILLEN and one that will join the many other first time landmarks STILLEN has achieved in the Nissan/Infiniti tuning world. CARB (California Air Resources Board) is the division of the California state government that controls all aspects of air quality and standards. With standards getting stricter it is getting more and more difficult to achieve CARB legality. CARB is recognized as the toughest emissions control in the country and is therefore recognized in all 50 states as an emissions standard for all performance parts. If a performance part achieves CARB Exempt status, it is recognized by all other states. The power the STILLEN Supercharger system delivers is dramatic, taking the factory 3.7L V6 from 332hp to over 500hp! The system is designed to work with both automatic and 6-speed vehicles, including convertible and AWD models. The STILLEN VQ37 Supercharger features a new cast aluminum intake manifold engineered specifically for this kit, complete air-to-water intercooler system, and boost is derived from a Vortech V-3 Supercharger unit. The V-3 features a quiet V-belt design, and a self-contained oiling system for easy maintenance. In the past year STILLEN has shipped supercharger systems around the world. Fantastic reviews and reports are coming in from:
Australia
New Zealand
Singapore
Russia
Thailand
Korea
Canada
Switzerland
Taiwan
France
Unite Arab Emirates
China
Hong Kong
United Kingdom
Not to mention all of the kits that have been installed with great success across the United States at Nissan/Infiniti dealerships and performance shops. This is a bolt-on system, capable of being installed by any qualified ASE-certified automotive performance shop, or at hundreds of Nissan and Infiniti dealerships across the country, or right here at STILLEN at our in-house install facility.
Once again, STILLEN has successfully accomplished all of its goals with another great forced induction solution for the Nissan/Infiniti vehicles.

STILLEN is proud to announce we are nearing completion for the Nissan 370Z / Infiniti G37 Supercharger System. As we approach production, we will be updating the progress as frequently as possible on our blog. We’ll start with the concept, and some insight into the development process.
This 3.7L supercharger development began in late 2008 and moved steadily through 2009. We had a bit of a delay in the development while the STILLEN R35 GT-R was prepared for Targa Newfoundland, but after that car was completed it was back to business on the supercharger! We have just started the new year in 2010 and we are excited to say the supercharger is nearly finished! Here is a re-cap on our development and some of the engineering that went into making this kit come to life!
When the 350Z came out in 2003, championship-winning driver for Nissan, Steve Millen (our founder) and our engineers sat down to discuss the main goals for the STILLEN forced induction solution. Given our history of developing products that were high quality and well suited to each platform, the consensus was clear; the STILLEN VQ35 Supercharger System had to achieve CARB EXEMPT status, and we had to offer a 3 year/36,000 mile engine warranty. The system had to be a turn key, ready to run kit and offer great power gains. To meet those rather challenging demands, Steve and the STILLEN engineers evaluated many blower options, but ultimately decided on the Eaton MP62 blower. It met all of the requirements and worked perfectly! That kit was a complete success and was the first supercharger on the market to achieve CARB Exemption and offer an engine warranty, with gains of approximately 100 horsepower at the wheels.
When the new VQ37 engines came out, Steve again sat down with the engineers to discuss what was the best method of forced induction for the 370Z and G37. Although the VQ35 roots supercharger was a complete success, we did learn a lot about what our customers wanted and what they would have preferred. We learned that some people do not want to change their hoods to accommodate the clearance for the supercharger. We also learned that even though some people want a CARB EXEMPT, warrantied kit TODAY, in a year or two they might want to upgrade the system to get even more power. Unfortunately the MP62 blower used on the VQ35 kit does not have the peak horsepower potential of some of the other forms of forced induction. It offers great bottom end but can get a bit choked off at high RPM when running higher levels of boost.
With these points in mind the ultimate decision was made to go with the Vortech Centrifugal Supercharger. The Vortech unit offers higher peak horsepower potentials and enables fitment under the hood for a clean installation. STILLEN has partnered with Vortech in the past to develop supercharger systems for other cars such as the Mercedes CLK430 and other Nissan vehicles like the Maxima and Xterra.
The STILLEN VQ37 Supercharger System will have 3 Stages:
Tuner Kit – All the hardware and equipment minus the fuel management. This kit should be ready in about two months or so. Look for it around the end of February beginning of March.
CARB EXEMPT Kit – This kit will be 50-state legal, and while it won’t have as much power as the other stages it WILL be street legal! More than likely this kit will be running around 6 psi. The release of this kit greatly revolves around the amount of time it takes CARB to grant us a test date and review our results. We can’t give a solid ETA on this because it really is up to CARB to grant us the EO#.
Competition Kit – This will be a pre-tuned race kit that will not come with any warranty and will not be 50-state street legal but it will be a bolt in kit for the guys looking for a bit more power but don’t want to bother with figuring out their own tuning. This kit will be developed along side the Tuner kit so look for it to be released around the beginning of March.
We invite you to follow along, we’ll be updating our blog with new information, status updates, dyno information, and additional technical information. Coming up is a detailed explanation of the cast aluminum intake manifold we developed for this system, and the benefits of the additional engineering STILLEN has put into this kit.
