    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 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!

    Great looking plug that includes o-ring and tapped hole and plug so you can attach your boost sensor.

    I ended up not needing this plug, I have an early 99 F250 and this does not apply to my model year.
