5 thoughts on “E3 Spark Plug Reviewed in 2021”

    1. they dont work in any small engine. they are a gimmick. they shroud they spark rather than leaving it exposed to the fuel charge.

  1. these are just gimmicks, positive posts and reviews done by sellers and manufacturers to sell a product. the fact is these plugs shroud the spark from the fuel charge, also electricity follows the path of least resistance, which means it will arc to the shortest distance each time. this can be anywhere on the outside electrode. they do not do anything to improve spark. they never or rarely work in small engines at all. whenever i come across one i simply throw it away and replace with factory spec plugs. usually NGK or Bosch. DO NOT WASTE YOUR MONEY!! they do nothing to help.

  2. No actual testing done here, just repeating the manufacturer’s marketing fluff and some opinion. What kind of “Lab” does no testing? Very disappointing…
