In all the years that I was parts manager at Ford dealerships, I sold thousands of Motorcraft filters - wholesale, retail and for everything from Escorts to LT9000s. I remember only 2 instances of defective oil filters, one was a bad gasket/seal and the other one had crossed threads. Some truckers were fussy and asked for Caterpillar, Fleetguard (Cummins), Luberfiner or Baldwin filters for their trucks but I don't recollect anyone asking for a Fram.
Personally - I'm a big fan of OEM filters, whether it's AC, Motorcraft or whatever brand the manufacturers use.
