After I washed my car, I thought to blow out my stock air filter since I already had the compressor running. I took it out, and cleaned it with air. Got out a lot more junk (sand, small rocks), than I thought. I noticed my hands got a coating of clear oil. It definitely wasn't water, and it wasn't motor oil. I just expected it to be dry, I guess. I don't have any intake mods, btw. Anyone else's stock filter feel a bit oily? Oh, I have 7500 miles on my 2k3 max.

 

never experienced that before

 

i was under the impression that the stock filter did a very thin layer of oil. one way to tell is pull the top part of the box loose and take a white rag and wipe the screen that leads to the maf. anyone with a k&n will notice it can get pretty dirty after while.

 

I recent bought an OEM filter from courtesy parts and it definitely had oil on it
