I had the Mopar cai on my 2012 300 SRT and I really felt like I lost power overall. I don't have any proof of that so it could have just been me. I don't mind gaining at least 10hp, that's a lot better than getting a cai and gaining no hp overall. I have always had a cai so to me it's like opening the hood and going "oh.....it's just stock." Lol, it's the simple things for me. Exhaust and intake. This time a little engine dress up and some other decals but I am not out there trying to roll up and run and gun next to a Hellcat or anything like that.
