So I know for JB4 you want Denso's to be gapped down to .022 or regap stock plugs down to .026-28 but what about the HKS plugs? I think they come pre-gapped at .028 is that what they should be or do you want a closer gap?

Thanks Terry!
 
You ever get a response? I'm curious about this as well
 
The gap is not plug specific. It’s application specific. Gap the plugs to the same as the Denso plugs.

.022 - .024

Whatever you use, try to maintain consistency.
