K&N Filter Oil Problems???
WARNING f-body owners
blackknight writes "The installation of an aftermarket reusable, oiled air filter may result in:
^ Service Engine Soon (SES) Light On
^ Transmission shift concerns, slipping and damaged clutch(es) or band(s)
^ Engine driveability concerns, poor acceleration from a stop, limited engine RPM range
The oil that is used on these air filter elements may be transferred onto the Mass Air Flow (MAF) sensor causing contamination of the sensor. As a result, the Grams per Second (GPS) signal from the MAF may be low and any or all of the concerns listed above may occur.
Tell me what you all think. Should i be worried or not with my K&N??
On my one and only import, (Audi S4 - wife's car) I installed an ITG filter which is more like an oiled foam element filter. The oil from the filter transferred onto the MAF and resulted in the car running like ****. Had to replace the MAF for about $400. It came pre oiled from the manufacturer and I think that they just put too much oil on it.
FWIW I like using the areosol can of K&N oil so that I can get a nice and even thin coat on the element. I always threw away the little plastic bubbles of oil they included with the kits. I try more for a dark pink and not so much a red color. What is that stuff anyway? Looks like Marvel Mystery Oil...

It's a common tendency to over-oil the filter. Less is better, to a point.

If you're not careful about oiling the filter, a descreened MAF is highly susceptible to contamination.
This is the easy way to avoid over oiling the filter. Works for me 100% of the time.
