I just read an article in 5.0 magazine on CAI intakes for the '05 GTs and there was a performance evaluation done on about 11 or 12 different intakes and Mike Bowen's intake did pretty well compared to the others. I don't have exact figures in front of me as I read it at the book store and am still waiting for my subscription copy to arrive by mail. Anyways, I just wanted to say I didn't know Pwrhwse did intakes and Mike if you are listening are you creating an intake for the 4.0L???
