    Comments about K&N Replacement Air Filter:

    I love this filter. Consistently better airflow combined with superb filtration. A little expensive, but worth the investment. I thought I'd "save" money and just put paper ones in, but I'm back here again. Fairly easy to clean and quite economical if you re-use it that way.

    Not worth it when it does damage

    • Incompatible
    • Low Quality

    Comments about K&N Replacement Air Filter:

    K&N will allow a little more air in at wide open throttle. The problem is it also lets in a lot more dirt. This dirt can coat and even damage parts like your Mass Air Flow Sensor (MAF).

    The only time I have seen them produce any real world returns is on a highly modified race car. And even then race cars, unless K&N pays them, will still run a paper filter as dirt can cause the engine to lose more power then it gains from the filter.

    So save your money, and your car, and use the regular paper filter made for your car.
