Use the E3 spark plug

I've been a mechanic since 1975, what people don't understand is that they don't have to put the spark plus that they call for in your lawnmower. I use the E3 plug. My lawnmower starts easy an I use less gas. Clean the plug an it will last a long time.

Low cost high value

I really could tell a difference… I mean not a crazy difference.. but my hawk 250 definitely ran better with this plug versus the one that came with it… I have also ran it with the iridium plug.. now they do last longer but to me the e3 feels the same performance wise
