E3 Spark Plugs E3.18 Spark Plug

Not just an odd looking spark plug

We have a 10 year old lawn tractor and were ready to junk it somewhere around year 3. I gave it a last overall tune up on every part I could find info on. The last thing I did was install one of these spark plug. I mean, I wanted to give the mower every chance of running well before throwing in the towel. Long story short, for the spark plugs part we began to get about double the mowings from every tank of fuel. When it failed 7 years later it just stopped firing. The plug looked clean when I checked it, but the slight coating was apparently enough to stop it completely after 7 years of use. In fact, I filed the old E3.18 and reinstalled it and it started right up. Then, I ordered a new one just for giggles.Read full review

Great spark plugs

Even though I haven't really used this particular spark plug yet. Put it in my generator, it does work. I chose this brand because I run them in my Harley and have experienced better performance and gas mileageRead full review

Added 3 mpg on my 40 year old bike, smoother running too

Work great in my motorcycle. Added about 3 miles to a gallon and a smoother transition off idle. My bike is 40 years old, and these livened it up a little bit. Peppy throttle response, quick acceleration, and better fuel economy. Will be using them in that bike from now on.Read full review

New Runner

Put these in our 1980 Yamaha Midnight Special and it runs absolutely 100% better with these plugs. We had tried a different set that was supposed to interchange but it made the motorcycle sputter & spit & it didn't idle very well. When we got these E3.18 back in the motor it runs like a brand new machine. Thanks a bunch. Worth every penny!! :)Read full review
