oil filters and oil pressure increase ?

There are two filters that are the best to use and they are both made by WIX. They are "WIX" and "NAPA Gold" Most engine builders recommend these filters. They are a high flow filter all my vehicles get WIX filters. I won't run anything else on my Diesel's either.

Buy some filters and cut them in half length wise. You will see the difference in drain back/ bypass valve and filter assembly.
