The Briggs World Formula spark plug offers top - notch performance, ensuring reliable ignition and smooth engine operation.

To use this spark plug, first make sure your engine is turned off. Remove the old spark plug carefully using a spark plug wrench. Then, screw in the new Briggs World Formula spark plug by hand until it's snug, and then use the wrench to give it a final quarter - turn. When installing, don't overtighten as it can damage the engine. As for maintenance, check the spark plug regularly for signs of wear or carbon buildup. If it looks dirty, you can clean it gently with a wire brush. Replace the spark plug if it shows excessive wear, usually every few thousand miles depending on your engine usage. This will help keep your engine running at its best.
