Dridge11: Dry the crap out of your K&N before you install it, use a hair dryer, leave it in the Sun, even bake it in an oven if you're feeling brave ... Then use it and monitor it for the first few times you take your car on a spirited run. Make sure there are no oil spots on the base of your air-box. If there are, clean it up with a rag immediately ... repeat until you see no oil spots and then you can use it as a higher performing regular filter ...

So before i install my K&N drop in , drying it out is a must?

That would be useful if the evo had a hot-wire MAF sensor!

What does the evo have? The basic idea is the same, spray with carb or contact cleaner.

man, I read this thread yesterday and decided to clean my maf today. I ran a k&n cone filter for about 5k miles and took it off because my car started running rich. It has been running rich for a while now. I took out my maf and it looked fine but i went ahead and loaded it down with sensor safe carb cleaner. M A N , what a difference. I wish I would have read this thread a long time ago. Shifting is sooo much smoother and no more backfiring when I slam through the gears. I prolly picked up 20 awhp. It feels like a totally different car. Thanks for the post and I highly recommend this to anyone who has ever ran a k&n filter.

Having owned a previous MAF equipped car, I have seen what K&N oil can do to MAF sensors. Like I said before, I stay with the dry filters...

What's funny is that K&N denies that their oil has any effect on the sensor.

7. Will a K&N filter cause my vehicle’s mass air sensor to fail?

At this time, K&N is unaware of any evidence that K&N air filter oil from a K&N air filter can damage or cause the malfunction of a MAF sensor, regardless of the make of the vehicle involved. K&N takes seriously any claim that one of its products is incompatible with its designated application or can damage or cause the malfunction of any automotive component. Such claims are thoroughly investigated and, when appropriate, testing is undertaken to determine their merit. In the case of MAF sensors, ongoing tests have shown that contamination from K&N air filter oil has not caused any failures or malfunctions of the MAF sensors in the test vehicles. K&N is aware that MAF sensors can become contaminated for a variety of reasons, unrelated to a K&N air filter (such as backfiring, blowby, leaking airbox or leaking intake duct) and that various methods have been used by some service departments and repair shops to clean a dirty or contaminated MAF sensor, such as spraying with an appropriate cleaner. K&N has not completed any tests as to the efficacy of such a process and, therefore, does not officially endorse or recommend any cleaning process. However, if given the choice of either replacing a MAF sensor or cleaning it, K&N recommends that the consumer ask his or her automotive dealer to attempt cleaning, before replacement. It should be noted that the presence of contamination does not mean the contamination was the cause of the MAF sensor failure. Sensors can fail for electrical or mechanical reasons, unrelated to any visible contamination.

Does anybody have a picture of the evo maf sensor wire?
Is it the thermistor looking wire behind the air diverter post?

The Evo has a von Karman vortex meter. When fluids flow past a bluff body (essentially wide and flat) vortices are formed. The frequency of vortex formation is proportional to the fluid velocity. Given the cross section of the housing you can calculate the volume flow. It's not really a MAF like a hot-wire. The detector itself is optical; acoustic is also common. There's no active element to clean but I suppose oil from a K&N could gum up the works.

After start -up my car runs lumpy between 3-4Krpm for the first mile in hot or cold weather. I have just had a dynoflash and K&N drop-in installed (only mods). Could this be causing it?

Just curious but do you guys just spray it with the sensor safe carb cleaner and then let it dry or do you guys use something (q-tip) to clean it as well.

I've had my K&N in for 25k miles now, and there's not a drop of oil in the airbox. I've owned 3 cars with K&Ns and have not had a single problem with any of them. Are you guys seeing oil on the sensors from the original install or more so after you clean it and re-oil it? Mine's getting pretty dirty so I need to clean it up pretty soon, I guess I'll be extra careful on how much oil I put back on it now. I noticed with my K&N that my car breathes a lot better down low, and I see improved gas mileage so I'd like to keep using it. So far so good for me, so I'll stick with it.

What sensor safe carb cleaner did you use? I don't want to end up messing up the MAF sensor. ALso did you just spray the cleaner on the sensor or use something to clean it as well?

Thanks.

When I first got my K&N it looked like it was over oiled from the factory. I soaked up as much of the excess oil using paper towels before intalling it in my airbox. I still would find a small amount of oil on the bottom of my airbox for qiute some time. I haven't found any residue on the sensor itself, but I clean it every once in while with electrical cleaner from Radio Shack.
