Replaced my old air heater
This AIH delete plug is a quick and easy mod! Its reasonably priced for the quality . My old air heater was leaking boost and makin a mess and this was the only replacement you should consider. Love riff raff products !

AIH Delete Plug
Where I live and drive I don't need heated air so I deleted the AIH and just kept the heater coil for possible future use. The coil does seem to create some turbulence so I did see a small performance increase. The Plug fit perfectly and if I ever want to re-route my boost gauge line I can go right to the plug.

Installed
Installed this plug when I did the up-pipes on my 2001. Easy to follow instructions and plug fit as designed. May have to get a boost gauge now!
