i pulled off my air filter to clean it, first time i clean it. i thought it was the same KnN i had on my old car, its not. it is one of those cheap autozone ones. my question is can i clean it and oil it with my KnN filter cleaner (it is a cotton filter), or do i need to trash it. im hoping it can get me through holydays, ive spent all my play money on my wife.
