This is a manufacturer sourced replacement part used with Kawasaki engines. A spark plug is used to deliver electric current from an ignition system to an internal combustion engine. After time spark plugs will become dirty or fouled. It is a good idea to replace the spark plug once this happens. This item is sold individually.
You should gap your spark plug according to the owners manual of the outdoor product you have.
You would need a spark plug wrench (or socket) to loosen the spark plug.

The tag on the outside of the shipping bag said BPR4ES but that was not the spark plugs that were inside the shipping bag. Could not use spark plugs.

Does this fit my product?Questions & Answers for Spark Plug
Does this plug come in sizes that require different sockets to remove? I have a JD X350 that takes a 3/4 socket and a JD S240 that takes a smaller socket.

Hello Scott, Thank you for your inquiry. While spark plugs do come as various sizes, each size/variation is assigned its own part number. This particular spark plug part number takes a 13/16 socket. We hope this helps you.
