        Comments about Motorcraft Original Equipment Single Platinum Spark Plug:

        I bought these for my 94 Ford F-150. The store told me the gap should be set at .054. This is also what the online spec shows. BS! Haynes says .044 for all engines for this particular year. In speaking with my mechanic he also told me that the gap should be set to .044. Maybe the gap should be set to .054 for some engines that use this plug but your stupid **s system should reveal this so that when a customer wants to work on his vehicle he can get the correct information from what is supposed to be a reputable source. I say [*] on your freakin system and you can have your d*** plugs back.

            A:

            Hi Dave, I'm glad to assist you! This Motorcraft Original Equipment Single Platinum Spark Plug - Part No. SP-502 is pre-gapped at 0.044"-inch from the factory. 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.
