Would RecommendThis spark plug has lasted me 16 years. It’s amazing how it keeps going and going. I’m thinking about putting this in my iroc-z camaro

Thank you E3 for finally making the "no fail" spark plug. We had trouble with starting our Generator, pulling , pulling, and pulling, then when we decided to pay the little extra and get the E3. Never will regret that decision, this starts every time on the second pull. Just recently, our Troy Built lawn tractor was not running well, first thought, lets put the E3 spark plug in this as well , and WOW, what a difference. Thank you for making a good product.

E3 spark plug
Would Recommendmy wife had a hard time starting our newer TORO mower. I put one of these babies in and not only does it start easier she claims it has more power than before and after repeated stops it starts first pull..definitely worth the extra cost. A+++

Decent, not a first-pull start though
I replaced a spark plug in my Brigg & Stratton engine on my Husqvarna 22" mower. It fits perfectly for the Autolite it was replacing, but even after running it for an hour it's still not a first pull start like the Autolite it replaced. However, the engine hits smooth, and runs well, so overall -- solid 4 stars.
