The main task of each spark plug is quite simple: it has to ignite the air-fuel mixture in a gasoline engine. However, the design of spark plugs and the materials used determine their performance and lifespan. Heat-resistant metals like iridium or platinum for electrodes, composite ceramic materials for isolation, a special shape and number of electrodes, and other solutions define the plug's heat rating and its ability to create a powerful spark. As for marine spark plugs, they have to comply with somewhat higher requirements regarding corrosion resistance if compared to their automotive counterparts.
Besides, the plugs for some boat motors feature certain visual differences such as the length or shape of electrodes. These differences can be minor and seem insignificant, but marine engines may have their own nuances justifying the use of such parts. In many cases, it's about different power and heat ratings, so reputable manufacturers such as NGK or Champion develop special models for boat motors to provide the finest performance and longest service life possible. In our online store, you can choose from numerous marine spark plugs sourced from leading brands and made to deliver reliable performance.
