NGK Resistor Racing Type Spark Plug - BR9EG (3230)
Features:
Wide heat range achieved using copper wire instead of conventional iron cores.
Copper dissipates heat more efficiently, cooling the electrode and insulator tip.
High-conduction copper and long nose insulator improve pre-ignition resistance.
Designed for high-performance engines.
