Factor Air Filter - Grease?
Truck is a '97 F-250 HD PSD.
I still have the factory air filter assembly and will until my warranty is up. After that I'm getting a Tymar, but for the time being the factory setup is staying.
I'm going to replace the filter soon and was wondering if we need to use grease (like the K&N) to seal it? I was thinking of using some just to make sure it seals, but should I keep the grease in?
Thanks,
