When changing spark plugs, always use Motorcraft double platinum's, or fine wire platinum's. They are designed to be
the correct heat range for your 2.3L, 3.0L, or 4.0L engine, as well as Ford's EDIS.
A word of caution about gapping these plugs. On the double platinum's, there are platinum beads on the center electrode, as well as the outer electrode:
Make sure you use the "wire" type of spark plug gauge, NOT the "circular" type of gauge.
When using the "wire" type of gauge, DO NOT use force to insert it in the gap, the platinum
beads can be easily damaged. To adjust the gap, bend the outer electrode close to the
spark plug threads.
Use one of these type of gap gauges:
