ah, thats only if theres way too much oil on it, right?

 

Absolutely correct! If it is oiled properly, there should not be a problem. I have been using mine for about 20K and its been perfect!

OOOO

 

In regards to the MAF, will I get an error or is this something that just NEEDS to be done?

I did "dab" the K&N with a paper towel before putting it in as I read that in a previous post.I did not see any excessive oil on the paper towel so I just threw it in without a second guess. I haven't seen/heard any issues.

Although, as it was PARKed in the garage, I stepped on the gas to get it up to 3.5-4kRPMs then let off.Right as I do that and before the RPMs rise there is not even a half of a second suck noise. Like air is being sucked in. Is this normal? Or can anyone with a 4.2 try the same thing and see if they can replicate? I never really did this before I replaced the air filter, so I don't know if this is SOP or not. I don't really want to put the old filter back in to see as it is a minor PITA.

Any help is appreciated.

 

If the MAF gets coated with the K&N oil, it will cause the MAF to fail and itwill throw a CEL because it will not be able to accurately read the air flow passing through the intake system.

OOOO

 

don't stress so much, it is just a drop in! Just easy on the oil, and you'll be fine. Been running them with no issues, My buddies 2000 S4 has had one for 3 years, NO ISSUES either.
