Anyone have any issues with their MAF crapping out with a K&N filter? Mainly after cleaning and respraying/oiling the filter.

Indeed. HKS is known for many more MAF issues than K&N. The K&N issues are like you said, after people clean and over oil them. Oil will get on the maf and screw it. Due to this and the fact that I (used to) have an oiled filter (WORKS) I got some MAF cleaner in case the MAF got oiled and it went limp mode. It never did though.

Alright sounds good... I think I am going to pick up a K&N to replace my AEM Dry flow... Because no matter what I do to clean the AEM, it stays black and I can never see any light through it..

15k miles on mine. Cleaned and oiled it 3 or 4 times now and never an issue. I've been running the same filter on the Outlander too:thumbup:.

I just replaced mine with a new one at 9000 miles. That was the dirtiest air filter I have ever seen. Ill spend 40 bucks for a new cone filter every 6-8 months, no biggy. I tried cleaning them on my cobalt, but felt i didnt do it right. Either was under soaking or over soaking when putting new oil on, so I just decided id buy them pre oiled and call it a day.

Thanks guys. Just wasnt to sure as I know the MAF can be picky and have heard of issues with them crapping out with the K&N filters from the oil.

if you over oil yes, the oil will splash onto the maf sensor, and cause false readings.

If you oil it properly, I dont see how this could happen, I dont really wanna take the chance thats why I just buy new filters.

to be extra safe you could probably pick up and AEM dry flow filter, they dont use any oil at all and chances are that would eliminate the problem all together :)
