Precise Fit: Spark Plug Compatible with Mercury/Mariner 200-275HP (1994-1996) and Johnson/Evinrude marine engines, perfect replacement for QL77CC/941M/BZ7HS10
Anti-Corrosion Electrode: Adopting copper core nickel alloy electrode and high aluminum ceramic insulator, it is resistant to salt spray corrosion and high temperature cracking, ensuring stable and powerful spark even under humid environment
Powerful Functions: Effectively improves problems such as difficult starting, lack of power, abnormal shaking and insufficient combustion, restoring the engine's optimal performance and faster acceleration response
Efficient Ignition: Precise design ensures stable release of high-pressure spark, promoting full combustion of fuel and enhancing the efficiency of engine power output
Durable Performance: After rigorous testing, it can still maintain a long service life under high temperature and high humidity environment, which is more durable than ordinary spark plugs and saves maintenance
