Spark Plugs E3.22 Premium Lawn and Garden Spark Plug with DiamondFIRE Technology, 14mm, 0.750-inch Reach, Gasket Seat, Pack of 1

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!

As good as the original equipment

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.

Finally I found a spark plug that turns on my Nat Gas Generator on the very first try. I have tried 3 different size plugs with no luck. I got it today and swapped it out from old and BOOM just kicked on very first try. Very happy I found this and I will definitely buy more.

Wow showed up early and was correct plug . Works great ! I bought other e3 plugs on Amazon and the sellers couldn’t get it right, ugh , I have to travel 1 hr to ups store because Amazon wants $8 to send back or use ups store. Come on Amazon you delivered it , pick up your returns

Super easy pull starts on my 208cc LCT Troy built snow blower. Previously I had to really yank it hard 2-3. Now a weak pull and it slowly starts then revs up. Significant difference…. Impressed.

The best plugs in my opinion. I have watched videos on YouTube of people installing these and the horsepower did increase a little I noticed that all my lawn equipment I’ve installed these in and it seems to always start up much easier and seems to run smoother and I truly believe it is giving it a little bit better combustion. I always square the gap to the terminal which is around 30,000s of an inch people who open the gap way up they don’t realize that the electrode will only arc to the closest spot of the ground next to it. The path of least resistance, it’s not gonna go to the very tall part of ground where they gapped it if that helps you understand what I’m talking about, I think the best thing to always do is square the ground to the electrode so it has a nice even spark across the whole surface.

Perfect fit for my generator, Briggs & Stratton. Ordered more than one. Kept us going during hurricane last year.

My snowblower is running like a brand new.
