NGK BKR8EIX Iridium IX Spark Plugs 2668 (4 plugs)

NGK 2668 Iridium spark plugs, are high-performance spark plugs, they utilize a fine-wire center electrode made of iridium, which has a very high melting point, allowing for a smaller electrode diameter and more precise spark. This design enhances ignition performance, fuel efficiency, and engine power. Iridium spark plugs typically have a longer lifespan compared to traditional spark plugs due to their durable construction. They are known for their consistent spark, which helps maintain engine performance over time. More Information on Iridium Iridium six times denser than platinum, and has a higher melting point, Iridium have extremely fine electrodes and able to retain excellent wear characteristics.
