The new Gen 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 on the G37 Coupe. This translates to an estimated 22 horsepower gain at the flywheel! For G37 Sedan owners, gains are 14 horsepower at the wheels. 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.
