Heavy Duty Spark Plug for Outboard Motor Fit BP7HS BP6ES BP5ES BPR6EY for Mercury Marine Boat Motors

Description: Upgrade your small gasoline power equipment’s ignition system with the BP7HS Iridium Spark Plug. It provides steady ignition performance, improves fuel combustion efficiency, and offers an extended service lifespan to ensure your equipment works reliably for longer. Features: 1. Long-Lasting Iridium Construction: The high-quality iridium alloy electrode tip excels at resisting high-temperature wear and corrosion. Compared to copper spark plugs, it lasts 2-3 times longer, helping you save money on frequent replacements. 2. Premium Ceramic Insulator: Made with 95% high-purity alumina ceramic, the insulator offers excellent electrical insulation and heat transfer performance. It effectively avoids flashover and overheating under high-load working conditions, so you get stable ignition no matter how harsh the working environment is. 3. Corrosion-Proof Metal Housing: The galvanized steel shell with anti-rust coating resists oxidation and erosion from fuel residue and moisture. It fits the engine cylinder perfectly to prevent air leakage, keeping your engine’s compression performance consistent. 4. Factory-Calibrated Spark Gap: The pre-set standard electrode gap from the factory ensures uniform and strong spark output. It enables full fuel combustion, enhances engine power output, while reducing harmful exhaust emissions and cutting fuel usage. 5. Stable Sealing Design: The built-in high-density copper core sealing gasket removes the installation gap between the spark plug and the engine mounting hole. It prevents gas leakage and loosening caused by prolonged vibration, boosting the overall operation stability of your engine.
