I am looking at purchasing a Cold Air Intake (CAI) but don’t know which one I should get. I’m interested in the Vararam http://www.vararam.com/g8.html but don't really know too much about the company. The stats for it look great. The other is the Volant CAI http://www.pfyc.com/pc/G83012/G8UNDER/Volant+Cool+Air+Intake+-+08-09+G8+GT+415960.html. Both are in the same price range. Any other suggestions?
