Not to be "that guy", but there are a ton of these threads already talking about CAI.
My impression from reading those threads:
Half would tell you they provide no performance increase at all. Something about how these new engines work, constantly adjusting fuel and air based on the engines needs or whatever. So, basically sound good and looks cool in the engine.
The other half would tell you they were ultimately happy with whichever brand they got, but most agreed the Mopar and vararam styles were too pricey. I've seen a lot of people with the S&B though.
At some point in the future, when I have money to burn, and no other parts to get, I'll probably get the mopar CAI, just cause it looks cool.
