NEW STILLEN Generation 3 Ultra Long Tube Intake for the G37 & Q60 Coupe

NEW STILLEN Generation 3 Ultra Long Tube Intake for the G37 & Q60 Coupe

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.

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.
