NGK SPARK PLUG R6254E-105 3949

NGK 3949 R6254E-105 Nickel Spark Plug

NGK Racing Series Spark Plugs are engineered to withstand the harshest engine conditions, providing reliable performance when you need it most. These high-performance plugs are designed for demanding applications where superior ignitability and durability are crucial.

Key Features:

• Fine Wire Electrodes: Features fine wire center and ground electrodes for enhanced ignitability, ensuring a strong spark and efficient combustion.
• Precious Metal Construction: Utilizes a gold palladium center electrode and a platinum-tipped ground electrode. This combination significantly improves ignitability, increases plug durability, and enhances anti-fouling capabilities, even under extreme operating conditions.
• Special Insulator Design: Incorporates special insulator nose configurations designed to improve throttle response, providing a more immediate and crisp reaction to throttle input.
• Corrugated Ribs: The corrugated ribs on the insulator prevent flashover, a common issue in high-performance engines, ensuring consistent spark delivery.
• Pure Alumina Silicate Ceramic: The insulator is made from pure alumina silicate ceramic, offering superior strength and excellent heat transfer properties to manage engine temperatures effectively.
• Copper Core: A copper core within the spark plug aids in efficient heat removal, further contributing to thermal management and preventing overheating.
• Triple Seals: Equipped with triple seals to prevent leakage, ensuring optimal compression and performance.
• OEM Kawasaki Racing Plug: These plugs are OEM specified for Kawasaki KX Racing applications, indicating their high level of performance and reliability for competitive use.
