I dunno if any of you guys have ever tryed them before or not, but i got some bosch spark plugs to go with my new wires, well after the install my car fliped out. it acted like it wasnt firing correctly. i double checked everything with the bosch plugs and it still sputtered, so i just put the old motorcrafts back in and it was fine. but yeah word of advice, dont get these plugs. the focus hates them. and my cars in great shape.
