I am also getting ready to start the process of removing my air box for one of the custom made cold air intakes like in the how to write-up on the custom intake and pcm mount. I have a 2004 GP GT1, and I was wondering if anybody could explain how to get the IAT sensor into the into the 4" 45 degree mandrel a little better (since this is where the write up got a little fuzzy for me) or if you have a better way to install the IAT sensor please let me know.
