What Customers Are Saying
Customers overwhelmingly praise these spark plugs for dramatically improving engine starting and performance across small equipment like mowers and generators. Most report engines now start on the first or second pull, run smoother, and respond more powerfully than before. Many note improved fuel efficiency and durability, with some reporting years of reliable use. Installation is consistently described as easy and straightforward. Reviewers emphasize strong value despite slightly higher cost, with several wishing they had switched sooner. A very small number report minimal improvement, but this represents isolated feedback.

Would RecommendThis replaced the brand. Previous model worked great. Too early in its life to review the new plug.

Reliable spark plug.
Would RecommendThe question is whether this spark plug is better than the traditional ones. I cannot say but it is no worse. I have used them multiple times over the years and replace them, as I do all spark plugs, by schedule rather than by decline in performance. The day I was shopping there seemed to be only the Honda Brand spark plugs and these that fit my lawn mower. These were much cheaper and so the question became a no brainer. I don't pay enough attention to gas usage to comment on that.

Well built and great design.
Would Recommend[This review was collected as part of a promotion.] Engines run better with these plugs. I've had good success so far. I've installed them on my Miller welder and my irrigation pump. And both run great.
