E3 Spark Plugs E3.16 Lawn and Garden Spark Plug with DiamondFIRE Technology, Enhanced Power, Fuel Efficiency, and Emission Control (Pack of 1)

After our very dry spring, we got deluged with rain. Yup, time to mow the lawn. My husband headed down and tried to fire up the old mower...nothing. I urged him to go to a local hardware store and purchase the plug so we could quickly take care of the lawn. He immediately turned to Amazon and realized that the extra day we would have to wait would not hurt us at all. Product came in 2-days and lawn looks great!!

I had carburetor issues on my string trimmer that I fixed and I noticed it was time for a new spark plug. I pulled out this same exact one. The last one lasted 3 years. I expect this to last at least another 3 years. It runs much better with this new plug and it is much easier to start.

I have an Echo Blower that the couldn't hold full force it would keep switching out like it needed some extra oomph. So I did tons of research on spark plugs by reading reviews and watching review videos. E3 and Pulstar are head to head as the Best plugs on the market. I'm a 3rd so 3 is my lucky number in which I ordered these E3's and OMG what a difference, the power is unbelievable it's like night and day. It starts up the first pull every time, a higher idle ,faster throttle response and that extra oomph plus some. I mean my blower has a little kick to it now when you use full throttle. These plugs are a must buy trust me. I already did the research for you so buy them as you will be very impressed. Oh and don't let the size fool you as they are a little bit smaller but a world of a difference!

Just as described

I don't post reviews very often but I felt I needed to on this spark plug. I bought this for my Craftsman Weedwacker Model 316.791191. This new plug had the same measurements as my old plug, but when I started threading the plug into the block I noticed it didn't thread straight in. It acted as if the plug was bent just passed the top of the threads. It threaded quite easily so I knew I hadn't cross threaded it and when it was screwed in all the way I could see a gap between the hex walls and the spark plug bore. I tightened it down as best I could without endangering the threads of the plug or cylinder head. I started the engine and immediately noticed a significant sputter and gas shooting out the small gap. I shut it off and put my old plug back in after cleaning it up as best I could and it fits and runs perfect. If the manufacturer wants proof I can submit photo's and video so they can see for themselves.I don't know if what I got was a manufacturing defect or what, but I will never purchase this brand ever again. It was cheap so returning for a refund is kind of pointless.

I have used E3 plugs in weed wackers and lawnmowers for years. But this E3.16 is incredible.I bought a new Craftsman weedwacker, Model # 79447 a couple of months ago. It ran ok, but was hard to start and kind of weak and stumbling. Checked the gap on the no name plug. Everything looked good but decided to put in the E3.16. Holy crap what a difference. Started right up, more power, smooth idle. Even sounded better. Make sure you gap the E3.16.

Starts my trimmer every time,love it

It’s a spark plug, does anything need said. It works…
