Seems to work as expected.
Would RecommendUnless there's quality control issues, and I just got lucky repeatedly, I'm not sure why there's so many 1 star reviews, if they in fact bought the right specd plug. I have various versions of this in my push mower, generator, and snow blower and so far, they've just worked. Just make sure you're getting one that exactly matches the original dimensions and you should be fine. Idk if I believe all their performance improvement claims, but all my stuff starts on the first pull, runs smooth and so ...
Airens Snowblower
Would RecommendLike the lifetime guarantee, perfect fit, Snowblower starts with half a pull and runs smoothly.

NOT a DROP IN REPLACEMENT
Would Not RecommendThese plugs are terrible. Trying to be the old spitfire plugs,l that didn't work then, and they don't fit. Completely trashed my Generac generator because LOWES claims it's a direct replacement. It has the wrong sized threads for a RC12YC plug and stripped the hole, cracking the head. Not only that but it hit the cylinder head. Beware..you're buying complete crap that doesn't fit properly here.
