E3

The E3 FirstFire spark plug helps your small engine run more efficiently. E3's patented Edge-to-Edge electrode design delivers an optimal spark to maximize performance, potentially increasing power and extending engine life. The result is a faster, more complete burn of the air-fuel mixture, maximizing power and minimizing wasted fuel that would normally exit through the exhaust. Whether you need a replacement plug for your lawnmower, snowmobile or ATV, putting the power of E3's DiamondFire technology to work is an easy way to keep your small engine running at its best.
