I installed a K/N filter about 40k ago and have no problems, but I had to take the truck into the dealer for some problems and he told me to get rid of the filter as it causes problems wiyh the MAF sensor! I know that on some trucks the oil from the filter is sucked into the sensor, my question is: should I pull the filter ( remember I've put 40k with no problem) or leave it alone?

 

just make sure you don't overoil it and occasionally take some electronics cleaner to the MAFS...both sides...should be fine ...mine is with over 50,000 on it

 

I have my K&N for 100K miles and no problem. Just keep the MAFS clean. I clean mine approx once a year.

 

What's the best way to go about cleaning the MAF sensor?? It's been a year since I installed my FIPK so as soon as it warms up around here, I plan on doing as such. thanks

 

I have used carb/throttle body cleaner and electronics contact cleaner (at different times), no problems.

 

though i use the electronics cleaner only...just don't try to clean it with a Q tip...they dont sell just the MAFS but the whole box.....300+new...junk yards 150

 

Jeff51,


Your dealer is incorrct in saying the K&N filter causes problems with the MAF sensor. As was touched on, just don't over oil it. The problem is induced by people putting too much oil on the filter after cleaning, and the oil will travel down the intake and stick to the sensor.
Leave the filter, just be carefull as to not put too much oil on durring cleaning. Also, let the filter sit awhile after oiling, and you can see if excess oil has accumulated at the low spots. If it has, take a cotton towel and wipe the excess away and you should be fine for installing it back in your truck. I have run K&N filters in all my cars and trucks with not a single problem....

 

I have had a drop in K&N filter and now have a FIPK...I haven't had any problems with my sensors. My father has had a K&N filter for over 100,000 mi. in his truck (4.6). Like others have said, elegantly, your dealer is full of beezwax.

 

so DO NOT use a Q-tip or any cottony fabric to remove the carb cleaner?? then there's no problems with leaving the carb cleaner on the MAF sensor . . . maybe hit it with some compressed air to knock the cleaner off?? i'm just under the impression that leaving anything on the sensor isn't a good thing.

 

The cleaner will evaporate leaving no residue. I wouldn't use compressed air, you may damage the sensor element (the fine wires that you're cleaning).

Electronic contact cleaner should say on the can "leaves no residue". As far as the carb/throttle body cleaner goes, I don't remember reading that on the can, however, I have never had any problems useing it in the past. I would recomend the contact cleaner just to be safe.
