Dear god. none of you sound like you know what your doing. The Bosch HR 78 NX spark plug is a super 4 plug that has 4 outer ground electrodes and uses surface air gap technology.
There is no need to mess about gapping the plugs as they are Factory pre-gapped electrodes.
Higher ignition reliability thanks to eight possible ignition gaps
Self-cleaning thanks to surface air-gap technology
Increased thermal range: up to three times as many cold starts possible as with conventional spark plugs
So don't mess about gapping your super 4 Bosch, Just fit them.
It really depends on the spark plug being used. But if you stick to the origninal spark plug NGK TR5A-10 it is supposed to be gapped a 1.0 mm since Ford has issued an in house service directive to reduce the gap from 1.3 mm (original) to 1.0 mm (present) 0.03936996
