Excellent spark plug!
This Briggs %26 Stratton replacement spark plug was correct for the engine size, and the gap was already set so it made this easy to install. The spark plugs are the OEM for Briggs %26 Stratton and should be used.for. optimum performance!

This plug is designed for a particular series of engine, it only fits in three different models. That should be listed in the details.

this is a fake item Walmart charged me for it but did not deliver it so I had to buy it at autozone. you should just go to auto zone first since you will have to after they don't deliver it but charge you for it
