Comments about K&N Replacement Air Filter:

I have always used K&N filters, just for the plain fact they will last the lifetime of your car and they are a superior filter. They also allow your engine to breath a little more. It might even give you a little more horsepower and better gas mileage. Eventhough I think the price point is a little high it is worth every penny.
