Oil Bypass Filter kits

I am thinking about adding an Oil Filter Bypass to my 318.
It has 2.5k miles on the rebuild. My mechanic at the time of the rebuild put in a synthetic blend oil.
I plan to go to the full synthetic at next oil change. I would also like to add a oil bypass kit to it at that time.

I need suggestions, recommendations and any results from those that have put one on your A body.

Thanx Ed
