Marine spark plugs are specialized spark plugs designed for use in marine engines. These engines are exposed to harsher conditions than land-based engines, including saltwater, humidity, and extreme temperature variations.
Marine spark plugs are typically constructed with materials that can resist corrosion and erosion caused by saltwater, and they are often coated with materials such as platinum or iridium that can withstand higher temperatures and last longer than standard spark plugs.
It's important to note that marine spark plugs come in different sizes and configurations, so it's important to select the right spark plug for your specific marine engine. It's also important to follow the manufacturer's recommendations for the maintenance and replacement of spark plugs to ensure the best performance and longevity of your engine.
