Bigger oil filter for Gen 4 truck

[Si Boosted Aira]

Interesting that GM engineers settled for a small sized Oil Filter. One would hope that they know what they are doing ie: is bigger better or just overkill. I wonder if it has anything to do with Synthetic oil being used exclusively? Oh well,,,nice that there is a choice of bigger available.

I use wix filters on my trucks. I always tell them my truck is a 2000 year model because the early 5.3s had a bigger filter than the current ones do.

Funny. Gen3 and Gen4 motors have different thread sizes for the oil filter.
