The K&N 69-7071TS Typhoon Short Ram Intake is a cold-air induction kit for the 2007-2008 Nissan 350Z with the 3.5L V6. It replaces the factory air filter and airbox with a mandrel-bent aluminum intake tube and a conical, washable K&N high-flow filter, so the engine draws air from a shorter, less restricted path than the stock setup. Buyers looking at this kit over stock or a cheaper universal intake are usually after a cleaner airflow path and a reusable filter they can clean and re-oil rather than replace. Search terms enthusiasts use for this kit include "350Z short ram intake 2007 2008," "K&N Typhoon 350Z V6 cold air intake," and "350Z reusable air filter upgrade."
Because this kit mounts where the stock airbox sits, fitment and installation should be checked before ordering. The intake tube is designed to work with the factory mass airflow sensor and crankcase vent hardware, so confirm your car's trim and sensor setup against the manufacturer's application listing. Plan on removing the factory airbox, transferring hardware, and reconnecting the sensor. Work carefully around the sensor connector and hose clamps, and keep the filter clean and oiled according to K&N's care guidance.
