Hey guys, I have a question on materials for the L_Intake. Why do you have to use the aluminum tubing? Wouldn't it be just as easy to use the 3" PVC pipe in its place? Is the aluminum used because it is 3" OD, so that it fits into the rubber? (I see that this ended up being more than one question.) Thanks for the help. I have had my car for 2 weeks and love it so far. I have picked up some really good info from this site. Thanks again.
