marine plugs
These are the same old reliable AC Delco Spark Plugs you trusted ever since you were a teenager in your 69 Camero except the metal parts are made of Stainless Steel so they won't rust in a Marine Enviornment and the threads won't get stuck in the heads when you forget to maintain your engine for years .

never champion
Always used ac delco plugs, never champion. I always had a fouling problem with any champion plug I bought, never with ac delco.

Perfect fit for my 1995 Trophy
Decent price shipped fast only thing that’s why four star Is that the packaging could be a lot better. These are spark plugs and you don’t won’t them failing when you’re out on the river. Nobody wants that. Buy xtra and check them for cracks.
