    Comments about K&N Replacement Air Filter:

    K&N high quality, as always. The filter comes pre-oiled, but does not include extra oil or cleaning fluid. This is a drop-in fit, which is even easier on the Volvo, since the filter housing is held on with spring clips that can be undone by hand. Don't install the filter upside down!

    Some cars experience mysterious engine gremlins after installing these filters because some of the filter oil makes its way to the MAF sensor. Give you MAF sensor a good cleaning (there are appropriate spray cleaners for this) when you install the filter, then if you get a check engine light, clean the MAF sensor again. This phenomenon is almost always due to someone overdoing it with the oil when reoiling a K&N filter.

        A:

        “EPA’s(Environmental Protection Agency) fuel economy estimates are designed to allow consumers to comparison shop. Your fuel economy will almost certainly vary from EPA’s fuel economy rating. This is based on a number of factors, such as weather, road conditions, your driving and maintenance habits, and your use of air conditioning.” K&N makes no general fuel economy claims, however K&N encourages you to try there air filter for yourself. Keeping air filter restriction as low as possible can be an important tool, among others, for maintaining high mileage.
