AC Delco quality, but be careful!
Bought these for my boat. Mercruiser 120. They seem to be genuine AC Delco SS. My caution is... BE SURE TO GAP THEM BEFORE INSTALLING! This should be a no-brainer for anyone with experience. I had brought them to my boat without gapping them. DUH! When I went to install, I found 1 out of 4 had the end electrode bent over right to the center electrode! Luckily I had a pocket knife that worked well to open the gap and set it compared to the others. Most likely happened somewhere along the shipping and handling process.

Omc cobra
Perfect fit and OMC recommended plug for an '89 OMC Cobra 4.3l (non h.o.) your spark arrestor cover should say the part number on a sticker as well for omc cobras.

I trust AC Delco plugs
AC Delco spark plugs are what I run in all my vehicles. I can't say that I've ever had one fail. These worked perfectly in my old Mercruiser 3.7 lt inboard/outboard boat engine. Fires right up every time.
