This is a ridiculous thread. There is no Purolator equivalent to a tough gaurd so you all are just comparing apples to oranges in yet another "let's all get off to how awesome Fram is" thread.
If you want to look at Purolator and Fram filters as a low/mid/high range option, you would be comparing the TG to the P1. Apples to oranges because:
P1 end and are constructed of metal, TG are not.
P1 has better efficiency, TG does not.
P1 has a completely different bypass system. TG uses a plastic spring loaded whatchamacallit
The only thing they remotely have in common is the grip tape finish, and even that isn't the same
Stop lying to each other with labeling this as a "comparetive" thread. Nothing could be father from the truth.
But as always, YMMV and Purolator is evil and Fram is the best and yada yada yada
