Replaced the plug in a Honda GX340 and it works great. Great quality with NGK.

My JD lawn tractor was depressed and tired. Sure it would still mow but I could tell that it was just going through the motions with no joy in its engine. These new plugs gave it the spark that it needed and it now looks on the grass with renewed vigor. Thank you Spark Plugs, thank you!

These plugs worked as you expect. NGK is a quality spark plug. As a former automotive shop owner, we used thousands, literally, of NGK spark plugs with no problems.

Exact fit for JD X540 garden tractor. Tractor was getting hard to start. Installed these and it started right up. Easy install. Raise the hood. Pull the plug wires. Unscrew the plugs. Install new ones. Re-install wires. Close hood. Start engine. Perfect fit
