I took my plugs out of my car and they were gaped at .75 and the Oreillys computer said .60 gap these plugs i bought were pre-gaped at .75 already. I looked in my car manual and couldn't find any spark plug gap settings. So is .75 the right setting?

Here are the specs for the plugs,

Spark Plug AC Type 41-921

Gap 1.52 mm (0.060 in)

15 Nm (11 lb-ft)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Splitfires are a sexy glamorous spark plug that is junk.
I don't think they are gap adjustable either.

The gap is .060

Pick up a set of delco or autolite (605) plugs
