K&N Dropin = bad MAF
Just wanted to let you guys know about what happened to me with the K&N dropin. I was getting custom dynoflashed yesterday and something was keeping the car for running right. Turns out all the extra oil from the pre-oiled K&N I was running got inside the MAF and it couldn't read correctly. A new MAF solved all my problems, but the K&N cost me $$$$
Do not use this filter IMO. See the dynoflash thread for more info if you want.

I really dont see that happening, alot of people have used that filter, all over the world and have never had that problem, Im not saying it could happen, but it would have to be dripping with oil.

Yes, it was a brand new K&N.
Well guess what bro, it happened.
I'm sure the MAF could be cleaned, but I didn't want to have a problem down the road. I'm going to try and clean my MAF and keep it as a spare.
This is not meant to be K&N bashing, I think they make a good product in general. I had great success on many DSMs with open K&N filters, but this evo filter is just plain over oiled IMO.

I didn't notice the problem either until the tune. Seemed to be fine before that. If you're not having a problem that's great but you might just want to check out your MAF for oil.

i have seen a couple that were pretty severly over oiled. we used a towel and the air hose to get rid of the excess and never had a problem. I still like the K&N but must agree that if it looks too oily it probably is so try to clean it off. simple easy fix.
you can also test your MAF to see if it is ok which it should be.

The filters come goo'ed up from the factory. I also had this problem, but caught it before it did any real damage. My MAF was COVERED in red oil, right out of the box. I switched back to stock filters. So the word to the wise is don't just throw it in there out of the bag, gotta wipe it down first. The funny thing is that I've never had this problem with the 3 other cars I used K&Ns with, only the Evo.

I did wipe mine down and specifically checked it for extra oil when I put it in. I would blow it out with a compressor first until oil was not coming out in any large volume. If I thought the oil was going to travel to the MAF I obviously would not have installed it at all for the minimal gains you get.

The car ran great on the dyno - no problems
Upon the road test I found a rough spot at a very low rpm section you would prob never use in normal operation - 1500 rpms FULL TPS
Step by step diagnosis confirmed a oiled up MAF sesnsor as the cause
IMPORTANT - the K & N drop in has proven very reliable and this is a very rare occurence
Still it is possible with ahevily oiled intake
My suggestion is it yuou have a oiled filter try to blow off some of the excess oil with a air gun before you inatll it
They really lay the oil on big time at K & N - too much
BTW - in two and a half years and prob at least 1,000 cars tuned on the dyno at pruven this is only the second time I found a problem during my on the road test drive
This shows why a careful post tune test drive is key to identify any issues so they can be resolved
