This is the "Long Tube" version of the Stillen Dual Hi-Flow Intake System for the 2007-2008 350Z. The restrictive factory air boxes have been replaced with two genuine, high-flow, K&N conical dual-cone air filters (designed with integral velocity stacks, using the venturi effect to accelerate air intake speed for even more power). They attach to long polished aluminum tubes, which adds additional horsepower, in addition to looking great. The higher air flow increases engine efficiency and power across the board, adding 10 hp - 9 lb/ft at the wheels. The Intakes sound "mild" under cruising situations, but really come to life creating an impressive intake note under acceleration. The filters sit inside custom-fitted urethane intake boxes, which ensure no hot engine compartment air gets sucked into the intake tract. Unlike other manufacturers who only partially shield the filter from hot underhood air, STILLEN has fully enclosed the filters, and designed the system to draw cold air from behind the grille, the optimum location. This creates a complete cold airpath, making these units the only true Cold Air Intake system for the 350Z. These urethane intake boxes can be left natural black or painted to match the color scheme of the car. CARB approved, 50 state legal.
