I know Motorcraft oil filters are actually Purolator, and they are one of the more expensive designs they offer. The Motorcraft is actually cheaper in price than what it should be. I always buy the Motorcraft. Also, Motorcraft spark plugs are made by Autolite. I'm not sure about shocks or anything on our cars, but I swear some of the newer F150s' rear shocks look like they might be Bilsteins to me, from being yellow and blue.
