I put in my K&N air filter the other day. How often am I supposed to oil it?

 

Hell, I think it says something like every 20K miles?

They claim that it acutally filters better and better as it gets dirty (up to a point) while not flowing any less. Definatly not nessicarry to clean and reoil it ever 10k or so.

You don't have to reoil it at all unless you clean it though.

 

Yeah, oil it after each time you washed it

 

I believe the instructions that come w/ it tell you to clean and re-oil it every 50,000 miles, but I'd probably clean it a little more often than that, especially if you're ever on gravel roads or something like that. I realize it might seem like blasphemy to take a mustang on a gravel or dirt road, but some of us are forced to do it from time to time.
