Osculati 47.558.84 – NGK BPR6HS-10 Marine Spark Plug
The NGK BPR6HS-10 (Osculati 47.558.84) is a reliable marine spark plug designed for 2-stroke engines where short reach, EMI protection, and clean combustion are essential. With a projected insulator and wider 1.0 mm gap, it ensures consistent spark performance, even under low-speed or cold-start conditions. The resistor suppresses electrical interference, protecting sensitive engine control systems onboard.
Key Features:
- Short thread reach (12.7 mm) for compatibility with shallow combustion chambers
- Heat range 6 – balanced for marine operation under varying loads
- Resistor type (R) – suppresses EMI/RFI for electronics-safe operation
- Factory-set gap of 1.0 mm – ideal for marine ignition demands
- Projected tip – better spark exposure and combustion efficiency
