which one is da best...?? u must have the intake to answer this question

 

Well most people agree that on the 5th Gen it's AEM. Personally I have a Iceman and it's only because it was cheapest at the time. The Iceman is nice for a few reasons, you don't need to enlarge the fenderwell to get it in, it comes in two pieces, so you can run short or long, and the plastic seems to not get as hot as the metal of the AEM.

An AEM has a consistent diameter the entire way, has the optional by pass valve, and its made by a better company overall.
