5.9 & 6.7 Cummins Best Aftermarket Oil filter

Cat Oil Filter Explanation Video
• CAT Oil Filter #396-45...
I didn't talk about fleet guard because I consider that OEM since it's made by Cummins. I run fleet guard 16035 & Donaldson DBL 7349 on my 6.7 Cummins for Hotshot Trucking. I change the oil every 8-11K depending on the oil I use and idle time.
