Well, I can't tell ya what the performance pick up was.....I did the Zoomers Exhaust at the same time! And now I'm ready to use the Predator tuner and 180 Tstat....which was just delivered!! During my research they all tested about the same.....My choice to use the Mopar CAI was to keep the Mopar Emblem where everyone can see it.....make the real performance mods where they can't be seen! I've been racing cars for 25 years Mopar, Porsche and Lexus (SCCA,PCA,WWSCC,BSCC)...never get tired of the quest for speed!
