Anyone actually ever screw up their MAF with K&N filter oil?

Anyone actually ever screw up their MAF with K&N filter oil?
I know the K&N's can pass oil and whatnot, but has anyone actually had MAF problems due to a K&N? The reason I ask is my car already has one on there from the previous owner and I'm wondering if it's worth spending a few bucks to buy a paper filter. I'd also like to think the K&N is worth at least 1 HP, eh?

I've been thinking of getting a K&N after I saw their in store demo/display. Very impressive at least at low flow rates. Its a good idea to clean the MAF occasionally despite what filter you run.

Thanks for the replies guys. Has anyone actually found proof that a K&N gains a few HP over a paper filter. When I did a search some people were saying it's good for no HP increase.

On my last dyno I pickedup 8rwhp and 8rwtq from switching to a holley filter and descreening the MAF. Now I know some of you will go nuts saying you should never do that, but if the tuner knows what he's doing then it shouldn't be a problem descreening it. I haven't had any issues since.

For those of us planning to keep our cars for years, this is an advantage. I certainly plan to keep my car, and at the time of filter purchase, the Holley Powershot was the preferred filter on the forums, so that is what I bought.
Not problems after the last clean & oil, but then I don't get krazy with the oil, either.

What advantage would descreening the MAF do?

The resultant turbulance will cause surging at idle & other problems.
Don't do it.

However, the calibration gets out of whack and could cause problems. Probably not worth the risks unless you can recalibrate the PCM.

Yeah, you don't benifit much from pulling the screen. Also, I ran a K&N for 3 years w/ no issues, re-oiled it...and set a code daily. Swapped to a paper filter and no issues (i also cleaned the MAF with some cheap spray cleaner from Radio Shack).
