So im trying to find someone who can tell me or tell me where to look for the difference between these 2 plugs - both Motorcraft - Ford. I cant find a motorcraft number, ford c/s says call the dealer and the dealer doesnt know. Hell, ford c/s actually gave me a number for a tech line and it ended up being there retails number for sales for clothing. Then i got a number for Ford Power Products which actually sells car generators!!! Im surprised anyone knows what the hell is going on over there.....
