Item Description

K&N 3/4" Breather Filter. This filter works great for the idle speed control on map sensor based single turbo setups. Rather then run 5' of hose to the intake, put a filter right on the ISC!

We DO NOT recommend using this to bypass the PCV system on a 7m or JZ engine, that can have a negative effect on engine performance! Disabling the PCV system is also bad for the turbo, it can make the turbo burn oil!
