Comments about K&N Replacement Air Filter:

I have used K&N air filters for a long time. I have vehicles with well over 200,000 miles with the use of K&N. These filters are high quality American made,they save u money over time because you just clean and re-oil.

    Comments about K&N Replacement Air Filter:

    This k&n air filter is worth the money. Can't beat the gas mileage in my 04 Ford Taurus 3.0 ohv ffv. I also use only full synthetic's in my car and I can get 36 miles per gallon on highway traveling at 60mph and 33 miles per gallon at 80mph. It did boost the city by very little to 22mpg. Thanks k&n for your product!
