NGK Iridium IX Spark Plugs ZFR6FIX-11 (4 plugs)

NGK 6441 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.
