AC Delco a proven Brand.
I've been using AC Delco products for years and never had a single problem. These plugs are a great value perform well and are made to last just like a quality replacement part should. Easy to install fit perfectly on my 3.7l 4-cylinder Mercruiser. 10/10 Kenny C. Riverside CA

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.

use the correct OEM specified spark plug
use correct OEM specified spark plugs..never overtightyen, taper plugs without a gasket..go hand tight and just a tiny bit more..DO NOT overtighten taper plugs..like barley 1 /16 of a trun after seated..
