and if you read the forums most of the people who ran K and N no longer do. Very fine line between perfect amounts of oil on the filter and too much. I have seen a lot of cars with them that have problems with the Maf . I would not run them on my bicycle. I know of lots of people who ran them and replaced them and now no longer have any problems. But of course K and n says otherwise . "
We are aware of the "urban myth" 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 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 challenge
