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!
STILLEN is excited to announce the availability of select AP Racing brake systems in a limited-edition caliper color – Competition Gray.
Racing fans will notice this color is exactly what full-blown race calipers from AP Racing look like. But unlike the race-only hardware, these are built for every day use with secondary dust seals, anti-rattle clips and extra corrosion protection. Finally – the best of both worlds with no compromises!
STILLEN is proud to release our line of high performance STILLEN Lightweight Standard / Underdrive Pulleys for popular Nissan/Infiniti applications. OEM steel pulleys, especially crank pulleys, can be quite heavy, robbing horsepower.
Upgrading these pulleys to a STILLEN 6061 Aluminum set reduces rotating mass, allowing for easier and quicker revving of the engine, resulting in increased performance.
In the case of underdrive applications, the reduced outside diameter of the pulley allows for the accessories to run slower, freeing up additional horsepower from the drivetrain, and putting that recovered power to the wheels.
STILLEN has a long heritage of machining precision pulleys for our supercharger kits, and used that expertise to create pulleys with a bold new design. Weight savings is dramatic, up to 80% lighter than stock and up to 10% lighter than other aftermarket pulleys. We have seen power gains of up to 10+ HP at the wheels.
SSTILLEN Lightweight Standard / Underdrive Pulley Features:
- 6061 Aerospace Grade Billet Aluminum
- Bold New Design Maximizing Performance, Strength and Minimum Weight
- 304 Stainless Steel Sleeves for Main Seal Contact Points For Durability
- Stock Timing Marks Maintained – Keyways are Precision Broached
- CNC Turned, Milled and Balanced from CAD Designs
- Underdrive Applications – 20% Approximate Underdrive

More applications of the STILLEN Lightweight Standard / Underdrive Pulleys are currently in R&D and will be released soon!
The highly anticipated development of the STILLEN Generation 3 Ultra Long Tube Intake (Part #402847) for the 2009 G37 Sedan is now a reality. Sedan owners can now benefit from the extensive R&D done with the 3.7L motor here at STILLEN.
Over 50 variations of this intake were used in the development on the 3.7L Coupe to get the largest gains possible. Gains on the G37 Sedan are 14hp and 10 lb/ft at the wheels. (Dyno below.)
The Generation 3 Intake System has a mild sound when cruising around, and an aggressive, undeniably powerful note when put under throttle.
Pricing and information can be found on the STILLEN Gen 3 Intake product page HERE. These are in stock and shipping.
More information and a video (for approximate reference on sound) is available on the G37 Coupe Gen 3 Intake Blog post HERE.
For this years SEMA Show, we were asked by Infiniti to build a G37 Coupe to take to their booth at SEMA, and we jumped on board. This year Infiniti had their own area at SEMA, and we were proud to bring a shining example of their flagship coupe for display.
We quickly got the 2009 Infiniti G37 Coupe into the urethane modeling shop and developed the Lip Spoiler for use with the Sport Model front fascia. As always, components are build our of durable urethane, for OEM fitment and quality.
From there we worked on a rendering, including a 3-tone paint scheme utilizing some BASF R-M Carizzma paint to create a charcoal top with a red stripe on the factory silver paint.
While in the modeling shop we also created our signature Roof Wing, as well as a rear deck wing that covers the chrome strip and follows the contours of the vehicle.
Combined with the suspension goodies reknown from the R&D department at STILLEN, and some new performance items just released (like the STILLEN Generation 3 Ultra Long Tube Intake Kit), not only does this G37 Coupe look good, but it’s ready to hit the track. Build sheet and products list below. Look for more photos and studio shots soon.

We’re proud to announce the release of our STILLEN Generation 3 Ultra Long Tube Intake for the G37 Coupe (Part # 402846). 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.

EDIT 10/8/08: We’ve had several customers in for this upgrade, and all are extremely happy. We got a chance to grab a quick video with a point and shoot. Better video to come.
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. 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.
We recently had a G37 at the facility, and we were able to do some testing on the G37 Headers, Cat-Back Exhaust, and High-Flow Catalytic Converters on the same vehicle to compare versus stock.
