    Comments about K&N Replacement Air Filter:

    It's obviously the cheapest, most efficient upgrade. Even if the results might be minuscule in some instances, it's supposed to improve fuel economy and add a very small amount of HP. I for one feel my car running a tad faster.

        Comments about K&N Replacement Air Filter:

        The best thing about the K&N air filter is that it is good for the life of your vehicle.You just have to clean and oil it periodically.The literature on the K&N air filter says you only have to clean and oil it every 50,000 miles.I have every intention of cleaning it every 12,000 to 15,000 miles or once a year.

        Just serviced the one from my truck. Cleaned up well but took a few times with the K&N Filter Care Service Kit Aerosol. Happy enough with the quality I went out and bought one for the car.

            Seems to increase RPMs and HP.
            Easy to clean, probably won't ever need to be replaced.
