Osculati 47.558.71 – NGK BPR6FS Marine Spark Plug
The NGK BPR6FS (Osculati 47.558.71) is a marine-grade resistor spark plug designed for 2-stroke outboards that require stable ignition and minimal fouling. The projected insulator helps improve flame travel and combustion quality, especially under variable loads and at low RPM. Its short 12.7 mm reach and standard 20.8 mm hex make it compatible with many compact-cylinder marine engines. A built-in resistor reduces EMI, protecting sensitive electronics onboard.
Key Features:
- Projected insulator tip for enhanced combustion stability
- Resistor type for suppression of radio and electronic interference
- Short thread reach (12.7 mm) compatible with many 2-stroke designs
- Standard heat range (6) suitable for a wide variety of applications
- Nickel alloy construction resists marine corrosion
