[QUOTE="Chris, post: 434041, member: 1"] Nothing substantial happens, trust me on that. An air intake will do nothing whatsoever on your JK as the factory airbox is not a weak point. A cat-back exhaust will do nothing either. Some will claim a 5 HP gain or something silly, but that's not something you can actually measure on a dyno as such a small number can be chalked up to nothing more than variables in ambient temp, engine temp, etc. If you're looking to gain more power, you're going to need to spend more money. Getting more air into the engine can increase power, but only when you open up the entire air pathway. That would mean intake, bigger intake manifold plenum / runners, ported head, bigger valves, higher compression, etc. Simply bolting on a cold air intake will do nothing whatsoever on these engines.
