spark plug gap

[ken inn]

actually, for lots of mods or high boost, use the W7DTC(colder, on bosch, the lower number means colder) which i used, or ngk BP7ET(ngk is opposite, higher number is colder).

The torque specs vary by the seat type of a particular plug and head material(iron vs aluminum). The reasons to torque them to spec are for adequate chassis ground return path, pressure sealing(obviously), and to eliminate vibrational backouts(walking). You want the arc from the coil efficiently jumping only the gap and not jumping cold through the spark plug threads to the head. I use antiseize in addition because it fills any vacant space and makes torquing(and removal) much smoother.

i also have torque sockets for the plugs. they have a magnet inside, no rubber, so it holds the plugs very nicely. they are click stop, at 18 toes/ft.

try the bosch W8DTC or the ngk BP6ET. triple electrode plugs factory gapped at .28, exact same heat range and reach for our cars. 3 electrodes are better than 1
