Fits well, sane quality as the oem installed
Works really well, it fits and matches the original spark plugs and very easy to install. Very affordable! It starts right up , quality is very good and didn't have to adjust the gap on spark plugs!

Fresh Spark Plug for the Mowing Season
Just what my push mower needed! Very compatible with my Craftsman M220 push mower. It was the right replacement part and workings just like the original brand B&S plug. Gap was correct right out of the box as my push mower fired right up first pull. Would recommend for anybody with a Craftsman M220.
