Best spark plugs I have used
Would Recommend[This review was collected as part of a promotion.] I have found the E3 plugs to be the most reliable plugs I use. I changed spark plugs recently in my mower (25hp Onan engine) and the old plugs looked ok. I looked up how long they had been in the mower and it was 4 years.

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!
