I have the Apexi power filter system and wondered if you can use the standard K&N filter oil and cleaner?

Thanks

 

according to the apexi website

The Power Intake is a maintenance-free dry-type air filter and will alleviate the problem of filter oil from "wet" air cleaners interfering with the air-flow meter

so i would say you can clean it with the kit but do not need to oil it after the cleaning.

 

I do lightly just to be on the safe side.
