Alrighty y'all, I've had a brain fart. I can't remember what the "optional" oil filter is. You know, the one that fits but is a higher capacity than the one parts stores list as for our car.

If anybody could help me out that would be awesome!

PF52 instead of the spec'd PF47.

An easy way to remember is the PF52 is used in the GM 4.3L engine such as the Bravada, Blazer, etc.

That'* what I was looking for, thank you!

I already it done with the regular spec, just bought a PureONE instead of a Wix so I could have synthetic media.

Interesting thing I noticed. My Silverado filter is just about the same size for a much larger motor.
