Lol, I sold mine because you just lose power in the summer. The car will bog down on a warm day, especially noticeable when you're sitting in traffic.

Read your intake air temperature with the stock intake, and then the K&N.
Stock will read lower (Hint: colder air is better)


All you're paying for is sound. That's it!

Well worth it man, just make sure that the kit you get has the right heat shield, the one I got has no hole for air hose coming from te center of the grill.
Your kit should have come with 2 different plates for the heatshield.
One of them has the hole stamped through it, the other doesn't.
