There's no single "spark gap setting" for a 2000 Ford Explorer. The correct spark plug gap depends on the specific engine your Explorer has (it came with several options). You
must consult your owner's manual or a reliable repair manual specific to your vehicle's engine.
The owner's manual will list the recommended spark plug gap for your engine. Failing to set the gap correctly can lead to misfires, poor performance, and damage to your engine.
