It works!
Would RecommendLike that it was in stock and my B&S seems to like it better than the last dead one. Strange how the champion died not during operation or perhaps that's to be expected. My Toro wouldn't start so before looking for a B&S mechanic I took the chance on a Spark plug replacement, and it was time for the air filter as well. Shazam, that was it, back in business.

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!
