Osculati 47.558.83 – NGK BPR5EFS Marine Spark Plug
The NGK BPR5EFS (Osculati 47.558.83) is a warm-range, long-reach spark plug with a built-in resistor and a projected insulator tip. It is specifically designed for modern marine engines requiring clean, stable ignition at low and mid-range RPMs, and is ideal for 4-stroke or EFI 2-stroke engines with electronic ignition systems. The resistor suppresses electromagnetic interference, while the projected insulator improves fuel burn and cold-start reliability.
Key Features:
- Warm heat range (5) ideal for general-purpose marine operation
- Resistor type for reduced electromagnetic interference (EMI)
- 19 mm reach with M14 × 1.25 mm thread for deeper combustion chambers
- Projected insulator tip improves spark exposure and combustion efficiency
- Nickel alloy construction for high corrosion resistance in marine use
