Everyone on one of the other Hummer forums say to stay with OEM plugs.
Everything else will run like crap.

I experienced the same thing with Bosch plugs. Always used them in for other applications but it does seem that OEM is the right way to go for the H3

AC Delco or champs, the rest don't hold up with the coil on plug packs. Been discussed over and over on hummer and chevy truck forums.
