E3.14 Spark Plug,Natural

This is for the only mower that I didn't have one in yet and I bought it because I was sold by three others in use for a couple of years now.Can't speak for lower emissions claim as I have no way to measure them, but I do enjoy faster starting and smoother running in everything they are installed in. Riders, push, single and twin cylinder.Have not had to test the life time warranty so can't speak to that.... hope I don't need to use it.Don't see one for the Ryobi 4 stroke trimmer/blower yet but even the RY4c standard plug seems tough to find..... at times

Makes lawn-mower run better. - Best spark plug you can put in a lawn mower or snow-blower. Starts better, runs stronger. I've used them for 10 years, best tune-up for any small engine, period.

I love these plugs. They may be a bit more expensive than standard plugs but they are definitely worth it. It's not that much more and considering how long they'll run the savings add up by not needing to replace them every season. I get on average 4-5 times longer out of E3's than the standard competition.

E3 spark plugs and just fantastic especially for lawn mowers. I put these in and now my mower starts easier and runs better than I did

Fit and works like it should in a Toro Powerlite

I have been using these in my Snapper Lawn mower for 10 years or so, They are fantastic.

best plug period,if your having trouble with small engines fouling plugs,this is youranswer.I had replaced a bad plug in my weed eaterwith a champion,it rana little better..replaced it with a E-3 and now it runs like new!

I bought these for my lawn mower and got 20-30 mins more run time per tank of gas for the same sq footage of lawn that i was mowing vs the original spark plug.Then i ordered some for my 1/2 ton pick up and i got more power off the line than regular autolites!
