FULL DESCRIPTION
NGK Resistor Racing Type Spark Plug - BR10EG (3830)
This NGK spark plug is designed for high-performance engines, featuring a wide heat range for superior operation. The copper core construction dissipates heat rapidly, cooling the electrode and insulator tip to prevent pre-ignition. Its long-nose insulator design further enhances the plug's resistance to fouling.
Key Features:
- Wide Heat Range: Achieved through a copper wire core, which dissipates heat more effectively than iron cores.
- Improved Pre-Ignition Resistance: Features a high-conduction copper center electrode and a long-nose insulator tip.
- Optimized for Performance: Meets the demands of high-performance engines, offering enhanced ignitability and acceleration.
- Fine Wire Center Electrode: A 1.3 mm nickel fine wire center electrode contributes to improved spark performance.
- Traditional Ground Electrode: Maintains NGK's commitment to high-quality construction.
- Sold Individually.
