Default ??? about NGK plugs
Do the NGK 55IX come pre gapped? Or would I have to gap them myself? Thanks

Last comment I read here on this subject said that they were pre-gapped and should be left alone. Still I think I'd at least check the gap and make sure they are all the same.

I think just about all plugs are pre-gapped anymore, but as MTurnbo said, double check to be sure.

Should be at .50, but most of us run .55 to .60
