For more information on how we educate and persuade the service provider to reconsider their position, see Mass Air Flow Sensor Information & Testing. We investigate the situation thoroughly and take full responsibility for resolving the issue. We take each complaint very seriously and see it as an opportunity to stop a consumer from being taken advantage of. Out of the millions of air filters we sell, we only receive a handful of consumer complaints each month that a dealership or service provider has blamed a vehicle sensor repair on our product. We all use oil for the same reason, it helps in the filtration efficiency of an air filter. There are also major brands of disposable air filters that are treated with oil. It is even more ridiculous because some car manufacturers use and sell air filters treated with oil on a regular basis. It is ridiculous, because no dealership or service provider has ever been able to provide us with evidence to support this “myth,” and in fact, our investigations have revealed that even authorized dealerships are simply speculating and do not have the test equipment necessary to know whether the sensor has failed or why. Once the oil is properly and evenly absorbed through the cotton, no oil will come off, even under extreme engine conditions. It is impossible because we know that the oil treatment on our cotton is very small (usually less than 2 ounces). No, it is both impossible and ridiculous. Will a K&N filter cause my vehicle’s mass air sensor to fail?

Question - has this actually happened to anyone, or is this just a theory that has been perpetuated and is now accepted as fact (like global warming)? I have heard from some on this site that K&N air filters will ruin your MAF Sensor.
