I know that it has happened, but, I wonder how many of those times itsbecause that person cleaned and re-oiled the filter and put too much oilon it??
The reason I say that is because I have ran K&N filters on probably my last20+ cars, and NEVER had that problem once...and I do not personally knowanyone who has had that problem?? Also, car manufactures do not voidthe warranty if you are running a K&N filter, nor do they put in the ownersmanuals not to run a K&N filter...go figure??
Here's what K&N says about what they call a myth:
Every stock replacement air filter we sell comes with this sticker, which we advise consumers to place prominently on their air box. The sticker is to alert service technicians that they should not throw away your K&N air filter because it will last for the life of your vehicle. When service technicians see this sticker it means “STOP SELLING THIS CUSTOMER DISPOSABLE AIR FILTERS OVER AND OVER.” In our opinion, this is why some dealerships or service providers may attempt to discourage a consumer from using a K&N air filter or worse blame a vehicle repair on our lifetime air filter. Most dealerships provide excellent service and fulfill car warranty obligations without issue, argument or tardiness. The rest of this discussion is about a minority of dealerships who are either misguided or misinformed.
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 a improper warranty denial, we offer our Consumer Protection Pledge.
But, to each is own... always do what you are comfortable with....
