One of the inexpensive ways of improving performance for your car is to let it breathe better. I have always installed K&N air filters on my motorcycles and my cars to get a little boost in performance. Well worth the investment

Easy installation, rapid overnite delivery, excellent price. Too soon to evaluate performance or mpg, but if these filters follow trend of K&N in my other vehicles, I anticipate mpg improvement of 10-15%.
