      Comments about Motorcraft Original Equipment Platinum Iridium Spark Plug:

      Replaced OEM plugs in a 1999 Ford Expedition 5.4L after the original plugs had 80,000 miles on them. Fuel efficiency improved about 2 miles per gallon. Easy to install except towards the back of the engine.

        Plugs work great. Had issues with autolite platinums so switched out to these. Truck runs like it was new.

                            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.

                            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.
