Did a search and could not find an answer... Are the NGK 10.5 plugs pre-tapped in the US market?

????????????

Do you mean do they come threaded to screw into the motor??

I hope so.........................

Or is it a type-O for pre-gapped?

If so, you should check the gap anyway to make sure it wasn't changed during shipping.

What should the gap be???? Good question, lets see what you get for a reply........

You can’t adjust the gap on the Bru’s, (i.e.BRU9EQ) on racing plugs you can, but that is a totally different story.
