whether the anti-drainback valve is orange, black, or blue in color & made of silicone or nitrile rubber is beyond any consumers' control; they are gonna have supply chain issues & are using what they have on hand...
my blue subaru usa filter is basically a 7317 sized extra guard or tough guard with a 20# or higher bypass valve spring...I just want the thing to filter properly for 5000-6000 miles!
