Have you ever heard of anybody using a K&N filter to have problems with their MAF sensor? I think the cases are extremely low. K&N warrnaties such issues as well so they most likely would pick up the tab for a new sensor if it's proven that their product damaged a device on your car. Sure it might happen, then again you could also blow up your transmission with a high performance clutch. The MAF sensor in our cars is nothing more then a tiny resistance wire which current runs through and warms it. The amount of air that blows on/past this wire cools it off and the resistance or current flow changes. Our ECU reads this current change and calculates the amount of air comming into our engine. Oil on this tiny wire will do no damage. There is probably a good amount of film built up on it over time anyhow. A quick spray with Intake Cleaner or a wipe with some Alcohol on a Q-tip cleans the wire off. I've already cleaned a few of the Nissan MAF sensors with a squart of Intake Cleaner and have had no problems since. If the cleaners don't distroy it, I'm sure a tiny film of oil sure wount either.

I use the K&N drop in filter in my 99 SE. I've had if for about 2 years now. I clean and oil it every 6 months. Never have I noticed any oil film or buildup at all on my MAF sensor or anywhere in the intake path after the filter. I trust K&N, they have been making filters for quite some time now and have a good reputation in the industry. Some of their filters are now OEM equipment on new cars. That itself should say something.
