Better Spark for a Better Burn
[This review was collected as part of a promotion.] I’ve used E3 for a few years now and they are everything E3 says they are! The milage is better, and the spark is better. I did take the time and on a small engine installed a regular spark plug and then an E3. The spark was significantly better. It was as they have said a spark pattern to burn the fuel charge better!
