Stillen 402847 Ultra Long Tube Dual Intake Kit 09+ Infiniti G37 Sedan
STILLEN Introduces the All New Generation 3 Ultra Long Tube Intake for the dual throttle body VQ engines.
STILLEN was the first national tuner to introduce a high flow intake for the Nissan / Infiniti VQ37 cars. Our first short tube intake provided a small gain 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 intake on the market for the VQ37 equipped vehicle’s. Our R&D team went engineered and dyno tested more than 50 variations before being satisfied that this system is the best that can be made for the VQ37 engines.
The new Gen 3 Ultra Long Tube Intake places two large K&N filters in front of the radiator. 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. On some applications such as the G37 a urethane splash guard is included in the kit to help protect the filter. This is only necessary on vehicles with larger grill openings from the factory. All kits feature a system of varied diameter tubing and steps to maximize air velocity.
The power result: A dyno-proven 20 horsepower gain at the wheels on the Dual Throttle Body 350Z, 18.5 horsepower gain at the wheels on the G37 Coupe and 17.5 horsepower on the 370Z. This translates to an estimated 20-22 horsepower gain at the flywheel! For G37/G35 Sedan owners, gains are 14 horsepower at the wheels. No other intake for the VQ can match these power gains!
Recommended installation requires removal of the front fascia clip (not absolutely necessary for some vehicles, 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.
