I can see why people are having problems with the maf sensor going with these K&N's. It is nice and oily! With my JWT intake I didn't have any problems with the maf sensor. It could be luck but it also didn't come oiled and I never oiled it. I'm not ripping on my new Berk, it's just an observation.

 

Lemme see if I have this straight. You ran a JWT Popcharger with a non-oiled filter?

 

If it was oiled I couldn't tell compared to the K&N I got from Berk.

 

Thats why Im going Apexi !
