MAF Mystery - Part 3 of 4 - What Does It Take to Foul a MAF

Part 3 of a 4 part series.
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 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.

What about spraying some K&N oil and then a little dust? The new MAF sensors don't have a hot wire burn off anymore. If the oil attracts dirt (I hope it does so it sticks to the filter) and a little oil is on the MAF and dirt then sticks to it, then what? Funny that they left that part out.

@TwiztidxxNinja Actually, if you review the video at 1:10, you will see that on the third test we did in fact add dirt to the system while spraying our oil directly into the intake with no MAF sensor failure.

@KNfilters it's probably not the fault of the company but of the consumer. cleaning the filter takes one day to dry out the filter and that cleaner is very strong I guess. Well my Two cents anyways. I'd take the KN filter any-day over the Paper

looks pretty convincing but they didn't test it over a long time period with the sensor operating and with some dust coming onto it.

Maf failure is more to do with how they are made, silicon contamination or electronic failure.

If something goes wrong dealers will always find something else to blame to get out of paying for new one if the cars under warranty.

It does not ruin mafs, and k&n have done tests and proved it.

with as many people saying that it ruins the MAF. i'm surprised no one has responded. It is VERY professional to allow comments. This says it all
