Replacement for OEM Plug
Would RecommendPerfect replacement plug for the OEM plug on our mower. Did a spring tune up on the mower and replaced a plug that was getting fouled out. This one did the trick. Mower runs great again.

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.
