    STILLEN was the first national tuner to introduce a high flow intake for the Nissan / Infiniti VQ37 cars. Their 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 they introduced the Generation 2 Long Tube Intake, featuring polished tubes, even better sound and a power gain over the Generation 1.

    Their continuing dedication to getting the maximum performance from each vehicle has led to the introduction of the new Generation 3 Ultra Long Tube Intake for the 370Z. This intake has a radically new design that provides dramatically better power than any intake on the market for the VQ37 equipped vehicles. Stillen’s R&D team 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 or AEM 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. All kits feature a system of varied diameter tubing and steps to maximize air velocity.

    The power result: A dyno-proven 17.5 horsepower on the 370Z. This translates to an estimated 20-22 horsepower gain at the flywheel! 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.
