Osculati 47.558.47 – NGK BPR7HS-10 Marine Spark Plug
The NGK BPR7HS-10 (Osculati 47.558.47) is a short-reach, resistor-type spark plug engineered for 2-stroke marine engines that operate under demanding conditions. Its extended 1.0 mm spark gap offers a stronger and more efficient ignition, especially under variable throttle and idle speeds. A projected tip design enhances anti-fouling performance, while the built-in resistor suppresses electromagnetic interference (EMI), protecting sensitive marine electronics.
Key Features:
- 1.0 mm factory-set wide gap for stronger ignition under load
- Integrated resistor minimizes EMI and RFI
- Projected insulator nose for improved fuel burn and fouling resistance
- Short 12.7 mm reach for compact 2-stroke outboard cylinder heads
- Nickel alloy electrodes for durability in marine environments
