Cost-effective alternative that works well..
I used these spark plugs on my 2018 Cub Cadet XT2 riding mower as part of the spring preparation. The spark plugs were well packed and arrive in great shape and at the appropriate gap. No issues with starting or operating the mower. These Harbot plugs turned out to be a great cost-effective option for me.
