Does indexing spark plugs (lining up the electrode to a desired location) make any difference in tuning? If it does where do I want the electrode lined up?
Align it with magnetic north on the main straight. Won’t do a thing performance wise but you can have a laugh watching others copy you
It won’t help enough to put you in the lead if aren’t already there. Does it hurt? No. For us I know we can see more return from focusing on other items but if you gave everything else dialed in I would say give it a try.
It’s one of those things that some people swear by and other feel it’s pointless.
I’m just happy if the plug doesn’t come out.
