It is...Flow > Colder Air Temps when your talking about a car that heats up air like no ones business with the crappy S/C we have.

Open cone.

pretty much everything should be in plumming section at a hardware store.

get a 3 to 4" coupler so you can join the 4" pipe to your throttle body.

You'll want to remove intake box. you dont need to remove all of it, just the two larger pieces and the rubber hose.

Drill a hole in the coupler for the IAT sensor thats in the rubber hose.

I wouldnt bother with putting it all the way in the fender though. Just get it close and leave it there.
