Wide heat range achieved using copper wire instead of conventional iron cores.
Copper dissipates heat efficiently, cooling the electrode and insulator tip.
High-conduction copper and long nose insulator improve pre-ignition resistance.
Designed to meet the needs of high-performance engines.

Product Summary:
Description: NGK 2689 BR9EG-N-8 Nickel Spark Plug, designed for Honda CR250R (2005–2007).
Details: A fine wire nickel plug with a traditional ground electrode and a special side electrode for improved performance. The 1.3 mm nickel center electrode enhances ignitability and acceleration, offering performance comparable to NGK EV or EGV types but at an economical price. While it does not match the durability of iridium or platinum plugs, it retains NGK’s high-quality construction for reliable performance in high-demand applications.
