Spark Plug AC DELCO, Sold in Multiples of 8, Pack of 8

Great quality, they fit my mercruiser 8.2l 502 perfect.

4 years later and the engine runs great and plugs look new. Very happy with these

Perfect for my boat with electronic ignition system

I found these plugs to be very high quality. As you always should, check and set gap.

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 .

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

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.

I have to regap them to 035 for my mercruiser alpha one engine they were almost @ 40. Price qas on point.

Bonne qualité

Perfect replacement from OEM plugs. If any issues after being in engine for a short while I’ll adjust my review.

Loved that it came in a set.

Great quality
