    We are aware of the “urban myth” (K&N News Story) created by a few dealerships that a vehicle's MAF sensor can be contaminated by K&N filter oil. No evidence has ever been provided to support this “myth” and three years of diagnostic testing by K&N has shown that not only is this allegation not real, it is not even possible. In our opinion, it is an excuse for a dealership and/or the vehicle manufacturer to avoid a legitimate warranty repair. In the last 4 years, we have sold over 10,000,000 lifetime air filters and received only a few hundred calls from consumers who are having dealership or service provider challenges. We believe that Dealership's or service provider's real incentive may be to discourage the use of reusable products so they can sell disposable products over and over. In order to provide consumers with added comfort that they will not be placed in a bad position by an improper warranty denial, we offer our Consumer Protection Pledge.

    The oil treatment on our cotton is very small (usually less than 2 ounces) and is a critical component of our filtration technology. There is nothing unusual about the use of oil as a tacking agent to improve air filter efficiency. In fact, certain Ford Motorcraft and Fram disposable air filters are treated with oil. This make us wonder if it is only the oil treatment from reusable lifetime air filters that is alleged cause a vehicle problem? The idea that oil comes off our filter throughout its life is truly ridiculous. Just like oil treated disposable air filters, once our oil is properly and evenly absorbed through the cotton, no oil will come off, even under extreme engine conditions. We have even conducted a test with an over oiled K&N air filter in which we flowed 1,000 cubic feet of air per minute for over twelve hours (few cars or truck could generate even 500 cubic feet of air flow). The use of an absolute filter confirmed that no oil came off the K&N filter tested, even in these harsh conditions.

    We have tested many MAF sensors claimed to be damaged. We can fully diagnose their condition and likely cause of failure. For a full discussion of our MAF sensor test protocol and findings, see K&N Mass Air Flow Testing Results and Findings.

    Not one of these suspected MAF sensors sent in for laboratory evaluation was shown to have failed due to contamination from K&N filter oil.

    We are the solution

    We are so confident about our testing and the quality of our product that we offer a Consumer Protection Pledge. So if you ever get in a bind with a dealership, call us because we are the solution.

    And for the record I do not use K&N filters and I am not compensated by them or any other company I just don't like seeing misinformation perpetuated.

    This is a photo of how good K&N filters. we have had to have several MAF cleanings since going to K&N. Never had to with disposables. K&N's are now in the trash.

    Right where they belong... Not to many people that drive diesels use any sort of filter with oil. They just don't go together due to the amount of air a diesel draws in and they do not filter well causing turbo damage. On a gas motor the lack of filtering just makes your oil dirtier faster and causes excess wear.

    Is that the one with all the fine dust from the area where you live?

    I though we had talked about that and the use of a pre filter for those types of environments.

    You have to choose the right product for your area there is no one fits all when it comes to any filter that is why you see for example several FRAM filters listed for different conditions.

    If you look at even the lowly lawn mower they use a foam filter over the paper due to the amount of dust/sand they are exposed to.

    Or just use a cellulose or nanofiber media and no dust gets through.

    This was from a drop in filter-no way to use a pre-filter that I know of.
