I just replaced the aging Autolite plugs previous owner had put in with Motocraft copper cores. Only $2.29 a piece and my gas mileage went from 10-11 to 17, got back a bunch of lost power, and it revs MUCH smoother.
Do you mean part number? Not sure how much more exact to get than Motocraft copper cores??you know exactly what those were? havent done spark plugs in this yet so gotta figure out what to put in them
Id get motorcraft. Can't go wrong. Most people recommend them. I just put a set in and it helped my car idle much smoother. I also put new motorcraft wires too
Autolite or motrocraft standard platinum's work fine. No need to spend $ on useless gimmicks that don't work in our old ass engines.
motorcraft. always a good chose to go with motorcraft on a ford
