wow...I am new here...can you help me? Geez guys, he just asked a simple question....and we are into a physics lesson again...lol....I love ya Max....anyway...there isn't anything wrong with making your own CAI...nor is there anything wrong with running the dreaded "devil horns"...which I am sure Rob cooked up one day when he cut an elbow wrong...they do look pretty mean...for me, having met Rob and became friends with Rob, I know he does his homework, he tests what he builds, add in the "professor" Woody, and they have a great product....doesn't mean you can't do something similar, but it is a good product...I have seen others, like Max's, that has the "look" and I am sure it does just fine for him.....and knowing he was probably "strong armed" by John to build another...lol....the point is, he asked for some tubing...just some tubing...personally, I think the stock air box met all the EPA standards for the auto industry, but it chokes down the air too much...that is why CAI aftermarket is so strong across the board in the auto world...anything just about, is better than stock...now straighten up and get along out there....is that enough hot air for ya....lol
