Runs better starts right up quicker.
[This review was collected as part of a promotion.] Runs better starts right up quick. Good low end power the biggest thing it starts up with no problem.

Better than normal plugs for faster starts
I have always updated and upgraded my spark plugs with hot plugs to help with easier startups but hate the price. Most easy start power equipment come with hotter plugs to ignite fuel mixtures. I also recommend non ethanol fuel like what we had in old days to prevent water vapor, varnish film and doesn't eat up rubber seals.

Love these "Plugs!"
[This review was collected as part of a promotion.] I use them in almost all my lawn equipment, that matches to the certain plug. Haven't had any issues what so ever with the plugs.

These are best for your outdoor power
[This review was collected as part of a promotion.] These you have to gap. You need these on all outdoor power gas engines. (The correct model of course). I have found they start gas engines faster than ngk or champion.

E3 worth the money
[This review was collected as part of a promotion.] E3 spark plugs always help my weed eater chainsaw and demolition saw run better and start better and they're good value for the price you pay
