Installed the Airaid dry filter CAI yesterday. Fairly easy. Didn't disconnect battery cable and when I started it, engine light was on and fans running full speed. Shut down, disconnected battery for 5 mins, fired back up, everything fine. Sounds great. I can see my engine and work on it more easily. Looks cool. For me, power gains are probably placebo (I have a 600hp Camaro). but, it does sound really good. Cons: Overpriced for what it is (~$350), cost of filter replacements (not sure of the longevity of those). A little concerned about the open top. My engine gets dirty. Not sure how some of these trucks I see posted have spotless engine compartments. Happy overall. Haven't noticed any MPG increases yet (after ~60 miles). Dual exhaust next!
