(Pack of 2) Champion Spark Plugs for John Deere M78543, M87543, RC12YC Engine

I usually tune up my mower every couple of years and the spark plugs is one of the things I swap out. The reason why I do it every couple of years is because of how cheap the spark plugs are and it keeps the machine running smooth. These are the same as oem parts.I haven’t had any issues with these spark plugs. They fit perfect and the quality is great.
