Don't waste your money on a CAI. A quality drop in is going to give you the exact same benefits. That would be a louder air intake swoosh and maybe a couple ponies.

I personally run a KN filter with no issue. Just make sure to let it dry in the sun for a couple hours before re installing. If you think thats too much trouble, go with a dry type filter.

At the end of the day... an OEM paper filter isnt a bad idea either. Just depends if you want to keeo buying those or clean the aftermarket once a year. Comes down to preference mostly.
