Ayuh,..... Welcome Aboard,... AC Delco MR43LTS spark plugs, 'n whatever wires ya want,.....

Boat spark plug wires live an easy, heat free life, 'n rarely go bad,.....

Matter of fact, I wouldn't replace 'em, unless ya find 1 that meters, Bad,.....

I've never had a problem with NGK. And for that engine, BPR6EFS.

For leads, OEM or 8mm aftermarket silicone.

I prefer NGK over the AC d's

I replace the wires every 30 years or when they get damaged trying to pull the boot off the plug....which ever occurs first
