I'll second that and read a similar article a while back. I specifically recalled the counterfeits with plugs and also bagged components. Also reiterate with the rest here to stick with OEM/Motorcraft. While my previous non-Ford vehicles might have been more accepting of aftermarket, my 3 Expeditions got nothing but Motorcraft from parts to especially fluids (except oil/filter). Cost is sometimes a bit of a hard pill to swallow, but I know I won't have to go back and do it a second time. As for avoiding the counterfeits (and for best price), I've been treated well with R*auto for partsFord has identified counterfeit OEM Ford parts, including spark plugs and ignition coils, being sold through retailers such as Amazon: https://fordauthority.com/2022/10/ford-files-trademark-infringement-lawsuit-over-counterfeit-parts/
For those that buy OEM Ford parts - make sure you trust the place you purchase them.
I buy my critical OEM parts from a dealer and a Motorcraft jobber - to ensure I get the real deal.
