Would RecommendI have switched to E3 plugs wherever possible in my power yard equipment, including lawn tractors, backpack blower, yard vacuum, and trimmer. Performance has been outstanding, and though I change plugs at the end of each outdoor season, looking at the plugs I probably don’t need to. Even after 8 or 9 months of heavy use on 19 acres of residential land, the plugs are not scorched or fouled with carbon deposits. I would recommend the E3 spark plugs for any heavy use equipment, even though they are...

Not for Husqvarna
Would Not RecommendPlug does not work in a Husqvarna weedeater. Would not stay running. Put the old plug back in and it ran fine.

Great plug!
Would RecommendI use E3 plugs in all of my outdoor equipment, both 2 and 4 stroke, and they are amazing! I have a chain saw and string trimmer that had always been a little harder to start, and now they can start on the first pull after sitting unused over the winter. I will not use any other brand in any of my equipment since I tried E3 plugs.
Ok price but prefer other options
Would Not RecommendJust not a fan of brand, engine doesn’t seem to run as good compared to an NGK

Perfect fit at a reasonable price.
Would RecommendNeeded this for our leaf blower and now it runs better than ever
Power when you need it
Would RecommendMy weed eater was getting hard to start and being in Florida there was a lot of trimming to do each week. My old spark plug was less than 6 months old and it was time to upgrade. With the E plug the trimmer starts easier, less aggravation and more work done.

Spark Plug
Would Not RecommendMore expensive than expected but worked. Would buy again.
I am a long time user of the e3 plugs and know first hand they are great starters and in for the long haul. I put them in all my small engines. And do it as soon as possible. Even if it is a new product. I have never heard one backfire like the other plugs do when they foul out. Maybe it's because I never had one that fouled yet. After around 15 or 20 years I still trust this plug most because it works very well.Thank you for something I can trust in.
