Hey guys, just wanted to warn all 3rd gen owners of these counterfeit plugs being sold on eBay and Amazon for both engines in this generation.

If you received Motorcraft plugs online and they have dark ink or old packaging you may want to dispose of them or return them....these also tend to lose plug torque and foul/misfire prematurely. Here is a video, things to check. It is hard to discern an oem plug vs the counterfeits which come in Ford packaging and are fake branded Ford:
