I dont bother with them any longer. I ran a Banks CAI in my JK with the Banks exhaust. The cat back gave me a bump and the CAI made noise....that's about it. I don't want to risk the potential filter issues for the noise. I wont put a CAI on my JL when it arrives, but did order the AWE cat back. On the JK the "power" was minimal...but there with the exhaust and MPG was up maybe 1 MPG over stock. The CAI made noise as I said...I’ve got a 3.6 in my 2020 JLU
I want the hole in my new vehicle, I'm just too scared to do it!I have the mopar CAI. But I am a moron who is willing to cut a hole in a new vehicle. Not much increase in sound at all, only noticeable with the top down. I did it for looks but did see a slight increase in MPG after the hood vent was installed.
Best thing you could do if you want more power is look into an aftermarket tune.
