              Comments about Motorcraft Original Equipment Finewire Single Platinum Spark Plug:

              Motorcraft finewire plats are the best you can buy for your OHV Explorer. They last a very long time. Add a tiny dab of antisieze on the threads and torque them to specification. Be careful when gapping them, never press against the finewire! They are usually close to spec.

              • Q:

                I have a 1992 Ford Ranger with a 2.9 Liter engine and I need these spark plugs. But these are pre-gapped to 0.44 and my manual says 0.42. Do I need to gap these to 0.42 or can I leave them like they are?

                What is the life for this spark plug?

                  A:

                  Normally, the expected life is 60,000 to 80,000 miles on an unaltered motor. If installed to a regular engine they would likely last longer than most people keep their car (barring any motor problems that can cause premature plug death). But, these usually come in heat ranges too cold for an unaltered motor and are usually used in racing applications where all bets are off.

              • Q:

                This is Part No. SP486: Motorcraft Original Equipment Finewire Single Platinum Spark Plug

                This is presented as original equipment for my 1994 Ford Explorer, however my 94 Owner's Manual specifies Motorcraft AWSF-42PP.

                Please explain the discrepancy. I definitely want to use Ford's specified spark plugs in order to exactly match the ignition system requirements.

                I bought these spark plugs and was told the spark plug gap should be 0.044 but my oweners manual which is 10 years old, said to gap at 0.055. I set them at 0.055 will this cause a problem.

                  It is best to gap them to what the owners manual states.
