Default Freshly Oiled K&N drop in filter

I recently re-oiled my K&N air filter and i was wondering if using too much oil could cause my car to run rich from the Mass air flow sensor becoming oily and reading incorrectly. If so how could i cure this problem? Is it possible to clean the MAF sensor or would it just be best to replace. This is pure curiosity but please only reply with honest answers
Thanks

i have a 2005 Wrx stg2

Go to Autozone, etc. and buy a can of CRC's QD Electronics Cleaner. Spray up inside, let drip dry for 30 minutes and quit oiling the crap out of your filter.

X2. More is not always better. This is a big mistake people make with reusable filters.

Do you mean by spraying the CRC inside the airfilter box? Sorry, I'm confused. I need to clean my MAF also but don't know where to start. The search bar didn't really help it that much also.

Just disconnect the wires going to the MAF and take out the two screws that hold it in. Now take the MAF and put it in a zip lock freezer bag. Now spray about half a can of non-chlorinated brake cleaner in the bag till it covers the MAf. Gently shake the bag and then let it sit for a few minutes. After that shake it a few more times and then take it out and allow to air dry completely. Put it back into the intake track and secure the screws. Plug back in the wires and your good to go. Easy huh? BTW the MAF is the piece of plastic with wires coming out of it right after the air filter box on the intake track. Hope that helps!!

The K&N instructions state that as long as the filter is oiled and covered with red or pink completely then it is enough. Even if you happen to over spray or over oil it will just soak through on the other side. It doesn't say anything about being harmful on the filter from over oiling. All your really doing is wasting your oil supply. I just cleaned and re-oiled my K&N filter couple weeks ago and my suby runs great again.

I see overoiled filters causing problems on a fairly regular basis.

k&n instructions don't have to pay to fix cars that have issues due to overoiling the filter

too much oil on the filter and the oil gets sucked through onto the MAF which causes erronious signal to the ECU which leads to driveability issues and poor overall engine operation

this is easily avoided by not overoiling the filter

so don't

exzactly so follow instructions and everything will be savvy. as long as all the filter gaps are properly coated to the point where it looks red. Then stop. People who over oil obviously didn't read instructions correctly or are ignorant.

You yourself don't sound too knowledgeable based on your previous post.

Just to give you all some idea, the word on the street is that from the factory these filters get a very light amount of oil on each pleat. After boxing and shipping the oil migrates throughout the rest of the gauze.

So basically it is not even necessary to darken the entire element on the first shot...just go lightly and let it sit for a while till the oil migrates.

he means spray the electrical cleaner into the MAF (if you remove the MAF sensor and look up into it, you'll see two parallel wires - those are what you are cleaning)
