This filter looks just like something GM used to sell, but larger yet.
see below for good article on bypass filters:

Amsoil is selling this modern version:

There is the cool factor in play here plus I want to see if the oil does run much cleaner than with just the stock filter, which I'm leaving in place.

I do wonder if a separate, lower micron rating, filter might be an idea for supplying a turbo bearing.
Thanks for the help guys.
