I was given a generator and it ran pretty good and it served it's purpose at that time but, I felt like it was struggling. I decided to investigate to see if I could make it better, then E3 came into my life. After doing some routine maintenance and putting this bad boy in there it runs much quieter, way more even. The starting was instant. The power was even across the rpm range. Couldn't be more happy and secure knowing that my generator will have my family's back when we need it. Will most definitely be switching over to E3s for my vehicles for their next plug change.
more power, reduced emissions, improved fuel efficiency, longer life, faster starts
