Strange Problem, Easy Solution. K&n Filter + Maf Issue.

[Kanaric]

Never had a problem like this before in any car. Basically the car was going into limp mode and intermittent loss of power above 3000 RPM. TL;DR the MAF was getting the filer's oil on it causing it to lose functionality, had to clean the MAF often with MAF cleaner and the car ran fine for a few days. I live in vegas where it gets 40+ degrees regularly so maybe that causes the oil to become more fluid and causes this problem. It's just weird. I've NEVER had this problem before with a K&N filter. Had a WRX and 350Z both with oiled filters like this and neither of them had an issue.

I guess this is a "cool story bro" post but it's just something ridiculous to me so I felt the need the post it.

Common issue with oiled filters, another reason why I just buy cheap filters and replace them yearly.

Or put the correct amount of oil (not much) onto them. Heaps of people use them no worries.

This was out of box, didn't even put anything on it.

Is there anything I can use to reduce the amount of oil on there?

Yes, you can bin the crap and use a decent cotton element, like Blitz/Greddy etc. Even a paper element would be better than the K+N.

lmao, ok.

K&N allegedly do extensive testing on their oil and filters against MAF sensors. If you believe that the filter is the cause of the problem, contact them for an explanation or refund.

I've had a K&N filter in my R33 for years and I have never had a problem.

Should I contact them to replace all the AFM's I have blown from running them, and all the customer's ones? I am sure they would love that email. lol.

Yes. If you have a problem caused by an unsuitable item it is their responsibility to rectify it.

Just email them. How hard could it be?

[scotty nm35]

Farkem. No way to prove they are at fault.

The issue isn't the oil on the hotwire, it is the dust that sticks to the oil and insulates it from the airflow.

[Ben C34]

Running the correct amount of dust through an engine stops the bores from glazing.

Fact.

I thought sand was the correct thing to use for self honing.

[GTSBoy]

Bon Ami is what I used to use.

I'm with Cassbo, no issues ever with correct oiling.

Happy to use OEM or cotton filters too.

I would still give the hot wire a tickle with contact cleaner regularly regardless.
