Does the job
To me these work much better than the iridium ones that cost 3 times more. My boat runs a lot better on these,

Typical AC/Delco quality and dependability
Excellent AC/Delco quality marine spark plugs. Thankfully these seem to still be made to the equivalent quality of yesteryear. I verified that all eight of these were gapped at .045" from the factory. We'll see how well the marine features (anti-corrosion, beefier construction) holds up with time, and I'll update this review if I experience any shortcomings over time. Otherwise, I expect these plugs to last 1000+ hours.

Crazily overpriced
Plugs are great, price is ridiculous. Better off going to rockauto.
