A few years ago I found a page dedicated to '97-? Grand Prix GTP's that had a detailed blueprint/diagram on how to build a cold air box/intake behind the drivers headlight to isolate the intake air from engine air. This was an extremely detailed drawing that the person supplying the dimensions made using sheet metal. I have recently found a shop that will build it for me, but I need those dimensions and pic. Please help me find this info so I can have one built.
Thank you.
