Good choice and the Home Depot guy was spot on! It was exactly what we needed.

Great replacement for my Toro mower

Just a yearly lawn mower servicing. That, the filter, the oil all from HD are always top shelf. Never a problem. Thx for keeping my Toro(also from HD)well and efficient for 20 yes.

It started the mower before the FIRST pull was completed ... treeemendous plug

My 20 plus year old Toro mower was running badly, hard to start/re-start, as well as stalling easily in high grass. The old spark plug was pretty old & worn. After putting in the E-3 plug, it starts easier and yes, it does seem to have a little more pep.

Always use these plugs in my mowers and snow throwers. Start strong and run cleaner too..

WOW - with no other changes, changing out the sparkplugs with the e 3s makes it idle smoother and start MUCH easier. I assume it makes more power than with the old J17LM Champion plugs I have used for years. Highly recommended!

It fits perfectly and has been working great. Good product!!!!

Cannot confirm all of the claims on the package, but my 10 year old mower started right up easy after putting in this plug, giving it an oil change, and putting in a fresh air filter. Had the same plug in for the previous year and as usual harder to start over time with wear.

absolutely the best plug I have ever used for ALL STHILE & HUSKY PRODS. I would give more stars but I had to change it my self. if all products performed this well, there would be no need for repairmen. Really super!

I've been using this spark plug for a short time but the mower started up right away and runs smoothly, happy to have the option for a replacement of the original one. Personnel at Home Depot near Doral also helped me identifying the spark plug type needed. Thanks for all!

Does it’s job well no complaints
