The QL86C Johnson-Evinrude-OMC spark plug is a high-quality ignition component designed for use in a variety of outboard marine engines. This spark plug is a crucial part of your engine's ignition system, responsible for creating the spark that ignites the fuel-air mixture in the engine cylinder, resulting in combustion and power.
The QL86C is a copper-nitride spark plug, which offers several benefits over traditional copper or platinum spark plugs. Copper-nitride is known for its excellent heat conductivity, allowing it to dissipate heat quickly and effectively, reducing the risk of pre-ignition and engine knock. This can lead to improved engine performance, increased fuel efficiency, and extended engine life.
The spark plug features a 0.6mm iridium center electrode, which provides a strong, reliable spark for easy ignition. Iridium is a highly conductive and durable material, ensuring a long spark plug life and reduced fouling. The 0.6mm electrode gap is suitable for a wide range of engine conditions, making this spark plug a versatile choice for many outboard marine engines.
The QL86C spark plug also features a porcelain insulator, which provides excellent insulation between the center and ground electrodes. This insulator is designed to withstand the high temperatures and harsh conditions found in a marine engine, ensuring reliable performance and a long service life.
The spark plug is equipped with a copper seal, which ensures a tight fit and prevents fuel and oil leakage into the combustion chamber. This can help improve engine performance and reduce emissions.
Overall, the QL86C Johnson-Evinrude-OMC spark plug is a high-quality, reliable ignition component that can help improve engine performance, increase fuel efficiency, and extend engine life in outboard marine engines. Its copper-nitride construction, 0.6mm iridium electrode, and porcelain insulator make it a durable and effective choice for marine engine owners.
