Strictly to the Mopar CAI- I honestly don't know if it's any better than any other well designed CAI. It does feel like it adds a little power over stock. The extra cash I spent on the Mopar was all for looks. A lot of the intakes I compared it too didn't look 'finished', they look like engineering samples.
I'm about to buy a MOPAR CAI for my 2013 R/T, from what I've seen it is larger than most. Is it worth it as far as performance. Also, which tuner would work best with this CAI?
