Are the New(Black ones)Mopar oil filters nothing but rebadged Purolator premium filters? Has anyone gutted one yet to see if they are the same. I was just wondering if they had the same amount of Media as a regular Prem.+ I see they dont have the silicone vavle so Iam guessing they are not a Pureone copy like Motorcraft filters? I know the old Mopar blue filters were junk. Thanks.
