I'm most definitly going with the C&L MAF, C&L Trueflow Tube and the Accufab 70mm TB for my 2003 Mustang GT. But which Plenum is the best? and if both are the same which one do most people prefer? I was also going to go with a 75mm TB but I've been seeing that you may lose horsepower if your car isn't modded. I see a lot of people getting this combo so it is one of the better mods to get?
