So i went to advance auto parts and was getting some oil to change my oil. I was looking through the store and seen they had K&N air filters. I looked mine up and they had one, so i bought it. Put it on in the parking lot. Went and got on the interstate. HOLY SHIT!!! Noticable performance improvement. I got up to 80 before the end of the on ramp. I was doing 110 before i realized it and i was only in 4th gear. I backed off. My car has a noticeable performance increase tho. The best $50 i have spent thus far on my car. Just thought i'd share my discovery.
