Osculati 47.558.48 – NGK DCPR6E Marine Spark Plug
The NGK DCPR6E (Osculati 47.558.48) is a compact, resistor-type spark plug developed for modern 4-stroke marine outboards that require precision ignition in tight engine compartments. With a narrow 16 mm hex and M12 thread, it fits in confined plug wells. A projected tip ensures clean combustion and optimal fuel efficiency, while the internal resistor protects sensitive electronics from EMI and RFI.
Key Features:
- Resistor-equipped to suppress EMI and ensure compatibility with electronic ignition systems
- Projected tip for better fuel burn and reduced carbon fouling
- Fine-threaded M12 × 1.25 mm body for modern plug designs
- Solid copper core for efficient heat transfer and long service life
- Corrosion-resistant construction ideal for marine environments
