        What is the gap size on these plug for my 2000 f150 5.4

          A:

          Hi SP VTEC 1, happy to help you! The Motorcraft Original Equipment Platinum Iridium Spark Plug (Part No. SP-479) requires .054 inch gap. Even though the spark plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that a modified engine with higher compression or forced induction will typically require a smaller gap settings.

        The description says Iridium but specs on Fordparts.com do not include the word iridium, just platinum plated copper. Can you confirm if these plugs are actually iridium? thank you

          It's a good question, Mitch! All the spark plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that a modified engine with higher compression or forced induction will typically require a smaller gap settings.

        How do I change the spark plugs in my 03 expidition?

        • CUSTOMER CARE

          A:

          Changing spark plugs is actually quite easy. Once you locate the spark plugs on your engine, just use a ratchet, a long enough extension, and the spark plug socket to fit your spark plugs. Simply unscrew the old ones and then insert the new ones. Screw them down by hand until the bottom out and then give them a turn or two with your ratchet and you should be good. For better assistance, I recommend getting a repair manual for your vehicle. It will be able to give you more detailed steps for your specific vehicle.
