Osculati 47.558.14 – NGK BP7HS Spark Plug
The Osculati 47.558.14 features the NGK BP7HS spark plug, a high-efficiency projected-tip plug used in 2-stroke marine outboards. The extended tip improves flame kernel position, enhancing fuel-air ignition and reducing fouling at low engine speeds. Designed without an internal resistor, it ensures maximum spark energy for ignition-critical marine applications. It is a direct equivalent to Champion L82YC and widely used in engines from major OEMs.
