K & N 57i - 57-0150 kit for 1.8 L silvia turbo
anybody uses this kit? does it actually help the car's performance or is it just a glorified and expensive flex hose that comes with K&N cone filter? from the pics that floating around in the net, all I see is K&N filter with some sort of bracket and maf adapter, and a flex hose.
if it just a flex hose, flex ducting hose can be had for cheap from your local homehardware store.
