Then why are you suing them?

Anyway, this is what they say....



7. Will a K&N filter cause my vehicle’s mass air sensor to fail?

No, it is both impossible and ridiculous.

It is impossible because we know that the oil treatment on our cotton is very small (usually less than 2 ounces). Once the oil is properly and evenly absorbed through the cotton, no oil will come off, even under extreme engine conditions. 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. It is even more ridiculous because some car manufacturers use and sell air filters treated with oil on a regular basis. There are also major brands of disposable air filters that are treated with oil. We all use oil for the same reason, it helps in the filtration efficiency of an air filter.

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 take each complaint very seriously and see it as an opportunity to stop a consumer from being taken advantage of. We investigate the situation thoroughly and take full responsibility for resolving the issue. For more information on how we educate and persuade the service provider to reconsider their position, see Mass Air Flow Sensor Information & Testing. We are so confident in our ability to resolve these situations and help a consumer fight back that we offer our Consumer Protection Pledge.

As a result of our standing up for consumer rights and providing assistance to resolve a disagreement, we have had 77 actual sensors sent to us by dealerships who claimed our product had caused them to fail. Microscopic, electronic and chemical testing revealed that none of the 77 sensors were contaminated by K&N oil (K&N Detailed MAF Sensor Test Results). What is perhaps the single biggest clue to what is going on is that over 50% of these sensors were not broken in the first place for any reason.

i think he meant "USED" ...and not "SUED"...:p

but to be honest i have experienced that the afm gets more dirty when i was using the KNN's, both the panels as well as the full blown open cone thats 12" at the base..!!!!
tired of cleaning afm that often, i switched back to stock airbox/paper filter..:)..
doesnt sound vroom vroom, but hey..cleaner..:)

that's one of the drawbacks, engine oil tends to get 'darker' faster too..
 
gets darker cos the cotton gauze filter letting in more impurities......which of course gets burned and more carbon being produced!

yes, if you overoil I do think the AFM can be affected.....just imagine the oil flowing thru and coating it up and with the dust, they bugger up faster too.

so the key is to oil the correct amount which is harder than it sounds....

anyhow I used K&N before on my older car with no significant improvement except the induction sound! and of course less no replacement $$$ of element.
 
Try the Pipercross drop in.... No Oil needed!

And yes I knew he meant USED.. I was just taking the mickey!

Thanks Pro, My typing error. Yes I mean "USED" not "SUED" haha......

Seriously my experience with Stock / K&N.....

My ride is manual 325, with the K&N filter can felt the pulling power is much better at mid and top end. But low is abit lousy.......

Stock filter, give better low end, but lousy at the mid and top end.
 
Out of the box, no...

But if improperly charged/cleaned with too much solution/oil, yes there is a possibility of MAF sensor damage.
 
The probelm is most people don't know how to maintain or try to save some money on using non K&N cleaner kit / products to charged / cleaned their K&N panel.
Secondly, wash with high pressure water and dry with air pressure gun. This will actually damage the cotton and open bigger hole letting more dust in and holding less oil.
I'm using K&N for both my cars (the GruppeM in my M3 uses K&N filter too) I used only K&N recharger service kit and rinse with tap water. Apply CORRECT amount of oil.
And both my car's MAF sensors are as clean + DRY as new. How I know? Because I'm a D.I.Y. freak dude....
