350z HR Stillen Generation 2 Twin Intake Kit Polished Long Tubes

Once again, STILLEN was the first to market with an upgraded intake system. Now we have taken this intake to the next level, utilizing additional testing and tuning to create both a short tube and long tube version of our highly acclaimed Hi-Flow Intake System for these vehicles.

We replace the restrictive factory air boxes with two (2) dual cone genuine K&N reusable high flow conical air filters. These filters are designed with an integral velocity stack and attach to our ceramic coated MAF adapters for our short tube kit, or newly designed polished aluminum long tubes. Replacing the factory intake tubes with the STILLEN design adds additional horsepower, and a great look for the engine bay.

The filters sit inside custom-fitted urethane intake boxes, which ensure no hot engine compartment air gets sucked into the intake tract. This creates a cold airpath, and we are proud to be the ONLY intake manufacturer to have developed a true Cold Air Intake for these vehicles. Unlike other manufacturers who only partially shield the filter from hot underhood air, STILLEN has fully enclosed the filters and draws on cold air from behind the grille, the optimum location.

These urethane intake boxes can be left natural black or painted to match the color scheme of the car.
