If you go with a K&N (or any oiled filter) be prepared to clean your MAF on a regular basis.

Theoretically you can achieve higher MPG with a K&N - but usually it's the opposite because of the way you'll end up driving. At least that was my experience LOL.

I installed my CAI and have wasted sooooo much gas since, I love the sound! :D
