You're going to get what you pay for, for the most part. Don't expect any noticable performance gains. Advertisers will claim you will gain 12 rwhp and that's just an outright lie unless you have built everything else under your hood prior to the air intake.
JLT is one of the best names I can think of in terms of "performance" but really its all up to which one you think looks the best under your hood.
Pull the air filter rubber silencer out of the air filter housing and drop in a KN conical air filter. This will net you about the same amount of hp as a CAI but at a fraction of the cost.
