I have run the Motorcraft 3095 and they are just ok. If you go to O'Reilly's auto parts and order Champion 425, that is the correct original plug. They sell for 19.69 each but they will last you forever. You can take them apart and clean them (use efferdent). I have also noticed my car runs excellent on them and I thought it did good on the 3095. What a difference.
