I've got a set with 5/8", 3/4", 13/16", and 18mm. Not sure I've ever used the 3/4".

Yeah, same, I checked earlier and yeah same, never have had a call to use the 3/4 either. Maybe it's a truck guy thing?! (Any truck guys here?, question above and a plea to use proper sized mudflaps. MY face thanks you!)

Either way, thank the wrench gods we all have Harleys (the metrics spark plugs I've encountered are no fun...... like angled different to the entry hole deep on the bike, I dread them every time ..... I check the harley plugs just to see the color!

from the previous page ironhead ron.nope,they're metric.probably 17 mm.i used an 11/16'' deep socket because it worked at the time.i've pulled them and use NGK DCPR8E ? i range colder than stock issue. my question about the splitfire was to verify if they were screamin'eagle plugs.haven't got an answer on that yet.it's annoying as hell when i click on this thread or any in the left side margin that it doesn't always take me the the current PAGE!

1st self-conscious me wants to confirm that THE site is annoying you and not my replies which do not contain your answer.

I opened a page to tryn Google some stuff, but it seems socket size is NEVER MENTIONED. As rare as it seems to be, and if it's poppin your crankshaft around ok, I'd assume there the same. But you never know until you know ... ya know (you seem to expect the brand to known, so could definitely be cloned, you'd have to see them next to eachothrr and to be really sure hope it still has numbers.)

Anyways, one last time for those in the back THANK YOU FOR MAKING PLUGS EASY FOR US HARLEY, WE APPRECIATE BEING ABLE TO WIRK ON/ INSPECY OUR BIKES!!!!

Makes sense, haven't a need for chainsaws or lawnmowers, as the HOA deals with that stuff.
