I was really bored today, so I decided to try and make the HD intake that some others have made over on GMFullsize...Before you guys ask, i'm trying to get pics but I can draw better than my camera puts out pics. needless to say, the SOTP feel is better, sharper response, and the noise is loud. I actually think its louded than my exhaust at WOT. either way, just wanted to let you guys know that it works quite well, and I only had $35.00 into it. I'm still using the stock airbox, with a k$n filter.
