NGK CPR8EB-9 (6607) is a high-quality resistor spark plug designed to deliver dependable starts, stable throttle response and consistent combustion. Built with durable materials and smart sealing features, it helps reduce misfires and keeps ignition performance steady even when riding in harsher environments.
Its trivalent metal plating improves corrosion resistance and helps prevent seizing during removal, while the copper core supports efficient heat dissipation. A pure alumina silicate ceramic insulator adds strength and promotes better heat transfer, and triple seals help prevent leakage for cleaner, more reliable operation.
Key features:
✅ Trivalent metal plating for superior anti-corrosion and anti-seizing properties
✅ Pure alumina silicate ceramic insulator for strength and improved heat transfer
✅ Triple seals to prevent leakage
Benefits of use:
🔹 More reliable ignition and smoother running through consistent spark delivery
🔹 Longer service life thanks to corrosion protection and robust construction
🔹 Easier maintenance with reduced risk of plug seizure during service
