Gap doesn't hold
I wish I could give Zero stars. I used these without realizing they were not champion plugs. I set the gap per my generators spec and installed them. After a few weeks of test cycles, the engine would no longer start. I called a technician to fix and it turns out that the gap in these plugs shrink and cause the engine not to start/run. I replaced with champion plugs and it resolved the problem but I'm out $335 for a service call.
