            A:

            Hi Rob, I'm glad to assist you! This Motorcraft Original Equipment Copper Core Spark Plug - Part No. SP-450 is pre-gapped at 0.040 inch from the factory. However, 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.
