Top Intake: STILLEN VR30DDTT Intake Now 50 State Street Legal 402856_IMG_01_2016_UP_Infiniti_Q50_3

STILLEN News Flash! The STILLEN Short Ram Hi-Flow Intake w/ Dry Filter for 2016-2018 Infiniti Q50 + Q60 (402856DF) vehicles equipped with the twin turbocharged VR30DDTT engine have received C.A.R.B. Exemption and are now 50 State Street Legal! These intakes are now legal for sale in California! Order yours today!

Top Intake: STILLEN VR30DDTT Intake Now 50 State Street Legal 402856_IMG_01_2016_UP_Infiniti_Q50_Q60_intake_Overall

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.

As a longtime specialist in the world of Nissan and Infiniti, STILLEN takes great pride in the engineering of its products. Having seen the performance potential in the new 3.0-liter twin-turbocharged V6, our engineers set out to develop an intake system that produced the greatest performance gains without triggering the dreaded “Check Engine Light” error or requiring a custom tune.

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.

It’s not every day that we release our Nissan 370Z demo car into the wild but when the guys from The Smoking Tire asked to stop by and take the car for a spin we had to oblige!  Matt Farah has been here before and went for a spin with Steve in the team STILLEN GT-R Targa rally car.  During that visit Matt saw the 370Z in multiple pieces as it was receiving the STILLEN treatment.  After multiple phone calls, emails, and text messages we were able to schedule a visit for Matt to get into the drivers seat of a STILLEN tuned 370Z.


Or check out the video at TheSmokingTire.com.

This car has been reworked from the inside out and from front to back.  With KW Variant III coil overs, STILLEN adjustable sway bars, SPC adjustable control arms, AP Racing brakes, Enkei GTC-01 wheels and Toyo R888 tires, STILLEN 370Z Cat-back exhaust, 370Z supercharger (CARB EXEMPT EO# D-436-20 and warrantied) to the STILLEN 370Z Bodykit In Urethane along with the Seibon carbon fiber hood.

All of these upgrades work together brilliantly to create an extremely capable and devastatingly quick Z. The 370Z’s notoriously underwhelming brakes have been replaced with a high performance set from AP Racing. The ride height has been dropped even further using a set of KW V3 Adjustable Coilovers paired with a set of STILLEN Adjustable Sway Bars and Adjustable Control Arms. To help ensure the suspension and brakes can effectively do their job, a set of ENKEI GTC-01 Wheels wrapped in Toyo R888 Tires helps get all 500 ponies to the ground.

Wanna see more? Our friends at /THEDRIVE also gave our 500HP Supercharged 370Z a go. Check that video out here:

STILLEN is proud to announce that the Infiniti Q50 Supercharger is now available for shipping! Q50 owners across the US and around the world who demand the very best have patiently waited for the STILLEN supercharger to enter production, and the wait was worth it!

STILLEN Infiniti Q50 Black Supercharger

500 Horsepower Supercharger

How does around 500 horsepower at the flywheel sound as a reward for your patience?

Add a dose of torque, better-than-stock heat management and airflow, 50 state emissions compliance and near stock fuel economy at low RPM. Now you’ve got the formula for superchargers done the STILLEN way.

We’re talking driveable horsepower too, suitable for daily drivers, canyon carvers and track days.

What does ‘driveable’ mean? Take an unsuspecting passenger for a low RPM cruise around town in your STILLEN supercharged Infiniti Q50. Keep a light touch on the gas pedal and they might be fooled into thinking there’s a bone stock motor under the hood.

They won’t suspect a thing….until you hit the town limit sign and crack the throttle wide open.

Scenery gets blurry-in-a-hurry as the centrifugal Vortech blower spins up to hyperspeed with a telltale hiss. The STILLEN designed and built intake manifold sucks in cubic yards of cool air. The remapped ECU fuel management module jacks the boosted fuel pump to inject the precise amount of high octane cocktail into the maelstrom.

Your right foot is orchestrating a symphony of controlled violence that delivers a linear, bottomless powerband. If you can peel your head off the headrest to sneak a glance at your passenger you’ll see instant enlightenment and heavy G’s at work.

Some of the exclusive STILLEN Q50 supercharger features include:

  • Boosts output to +/- 500 HP at the flywheel
  • Compact design means no hood replacement required
  • Front-mounted compact heat exchanger maximizes cool air flow to vital engine cooling components
  • In-manifold air-water intercooler chills air charge at engine entry point for maximum efficiency
  • Redesigned intake manifold for increased airflow and torque
  • Utilizes Vortech V3 supercharger – fully sealed, quiet, upgradeable and reliable
  • 50 state legal
  • Available 3 year/36,000 Powertrain Warranty

STILLEN Infiniti Q50 Black Supercharger


Before donning the STILLEN logo, this supercharger was thoroughly tested to ensure maximum quality and performance by our in-house Research and Development team. However, to truly test this supercharger’s limits, it was put through its paces and driven from STILLEN headquarters in Costa Mesa, CA to the SEMA show in Las Vegas, Nevada and back by STILLEN Vice President of Business Development, Kyle Millen.

After the drive, Millen said: “The Q50 drove exceptionally well the whole way. There were a few stretches of road where I was able to open up the car and I was very happy with the power delivery as well as drivability.”

With results like this during testing, we have no question about this supercharger system’s quality and reliability. As such, we are offering a 3 year/36,000 mile manufacturer’s limited engine warranty on this kit.

Fresh off the dyno at the STILLEN performance shop, we snuck a glance at a 2013 370Z Nismo that just got a STILLEN supercharger installed. Wow, does it look good on those Bronze Burst Forgestar F14 wheels, paired with Hankook Ventus V12 Evo2 Tires, and it can really make the power!

The Wishlist

Like most of our supercharger installs, the owner of this Z was looking for more power to enjoy as he cruised the streets on weekends. As a the370z.com forum participant, he knew that his first stop should be STILLEN. As soon as we got his car in the shop, our experts went right to work on the supercharger install.

Want More Power? Get a STILLEN Exhaust!

After the install was complete, we put the 370z on the dyno to see how much power it was making. Unfortunately, it wasn’t quite what the owner was looking for. To get a bit more, our experts suggested he try a STILLEN 370Z cat-back exhaust (504355). As soon as the exhaust was installed, we got the car back up on the dyno and it started churning out the power… 404 HP (rear wheel) and 294 ft/lbs torque!

This has certainly been the summer of superchargers for the STILLEN performance shop. For as many supercharger installs our ASE certified mechanics have done, none have been better looking than this STILLEN Supercharged Infiniti G37 show car that got a STILLEN polished supercharger for Infiniti G37. From a custom exhaust to carbon fiber body components, this was one very sleek looking car!

STILLEN Supercharger, Seibon Carbon Fiber Body Components & More!

Seibon Carbon Fiber Body Components

The first step in getting this vehicle show ready was getting the Seibon carbon fiber added to its body. From lip to trunk, this Infiniti G37 is decked out in carbon fiber and it looks fantastic! Here’s a full list of the Seibon carbon body components that can be found on this G37:

Seibon Carbon Fiber Specs:

  • Made from grade AA, high-quality carbon fiber
  • Comes with a clear coat and UV coating to protect against fading and discoloration
  • Superior production process yields an impressive carbon/resin ration
  • Hand crafted by expert craftsmen with over 15 years’ experience

STILLEN Polished Supercharger

As supercharger installs go, it’s pretty exciting for the STILLEN performance shop to install a polished blower. Most of our customers are all about the power and less about the looks, so they opt for the satin supercharger. Since this costumer chose to go with the show-quality, STILLEN polished supercharger we were pretty excited to see that beautiful sight it would be sitting in the engine bay and this blower didn’t disappoint – it is exquisite.

No show vehicle is complete without wheels and a lowering kit and this show G37 is no different. The owner installed a lowering kit and added Stance Wheels for a sleek, custom look. To make sure the car sounded custom too, the owner also added a custom exhaust. Now that the details are starting to come together, we can’t wait to hear how this vehicle does in the shows it enters. Rumor around the office was that the owner was looking to enter it in the Las Vegas SEMA show… We sure hope to see it there and really hope it wins!

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.

Nissan Titan Air Intake

STILLEN Air Intake for Nissan Titan CARB EXEMPT EO# D-436-22 is good for a 15WHP / 27WTQ Power Gain At The Wheels

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 applications STILLEN 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.
