The K&N 69-7078TS Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Nissan 370Z and Infiniti G37 models. The restrictive factory air filters and air intake housings are replaced by the K&N Typhoon air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. This allows your engine to inhale a larger amount of air than the factory air intakes. More air means more usable power and acceleration throughout the engine's RPM range. The 69-7078TS air intake comes with dual black rubber topped K&N high-flow air filters and heat shields that install into the previous air box spaces.
