Spark plugs are among the central electrical components of a Moto Guzzi and are largely responsible for igniting the fuel-air mixture in the engine. These components are made of high-quality materials such as copper or platinum and are optimised for efficient combustion and performance. Spark plugs must withstand heat and pressure in the combustion process and are designed to ensure reliable ignition over long periods of time. Choosing the right spark plugs as well as regular inspection and, if necessary, timely replacement are crucial to ensure optimum engine performance and reliability.
