Review: Upgrade for a Duromax 10000EH generator over stock with brighter spark - After three winters of running on the original spark plug, I decided it was time for maintenance. Although the generator was running fine, it did take an extra 5-10 seconds cranking to fire up, and was giving off a little more exhaust than previous years. Our generator is a hybrid and we run it exclusively on propane. When I removed the original plug, there was brown discoloration on the old plug but it wasn't terrible. Clearly needed a refresh or cleaning at least but I opted to replace it. I checked the gap on the E3 Spark Plug E3.22 and was pleasantly surprised it was already gapped correctly. I connected to my plug tester and cranked to verify spark and it gave a big bright spark. So I installed the plug, and tested the generator. It fired RIGHT up, almost on the first crank. It ran very smoothly as well. Nothing else had been changed. So I decided to add a power load and found that the generator must be making more power because the load did not drop the engine RPMs nearly as much as it had been doing previously. These plugs get good reviews elsewhere and I will echo the sentiment. My next test will be to see if I get more efficiency out of a single tank of propane from a cleaner, more efficient running engine. If you haven't changed your plugs and changed your oil in your generator before winter, do it NOW!

### ⭐⭐⭐⭐⭐ Great starting spark plug.
*by J***E on October 28, 2023*

I've used this E3 series spark plugs for my lawn mowers and snow blowers. They work very well, and seem to give a quicker start and last the whole season. They probably would last longer, but I change them out every season.
