My vote is NOT a CAI I had one from afe and it made my idle Revs bounce and it disconnected from the intake housing every 2-3 weeks. The design was sh*t and they haven't changed it as far as I know. I ran it for about 2 years and went back to the stock intake...tbh much better performance with a sealed intake. Just upgrade ur filter if u wanna do any intake mods
