First I want to say thanks to the info on the air box mod. I did it on my '99 and it definitely gave it a bit more pep. Second, in order to do the mod, I found it highly effective to use a Roto-Zip bit in a drill. It makes for a very clean cut and only takes about 3 minutes to do the whole thing. Sure beats the hell out of trying to do it with a utility knife !!!
