About E3 Sparks

“We have a 1997 Isuzu trooper with over 225,000 miles and were going on a trip about 2,000 miles long, and stock mileage is 14 to 17. After using your E3 plugs our mileage went up to 18 to 23 mpg depending on the driving hills or flat road. We love your plugs and are worth every penny, they paid for themselves just on this trip and more power too! Thanks”

Race Proven

Over and over again, the new plug burned fuel more efficiently, improved power response and cut toxic emissions. Today, E3 remains dedicated to reducing greenhouse gas emissions by limiting the amount of unburned fuel.
