Designed to deliver optimal performance, it features E3’s patented DiamondFIRE technology, which creates an edge-to-edge spark path for improved combustion. This innovative design replenishes the spark zone with a fresh fuel/air charge, enhancing engine efficiency and power output. By generating more pressure against the cylinder, the E3.101 ensures more effective utilization of available fuel, boosting performance and reducing waste. The unique DiamondFIRE ground electrode also enables faster flame propagation, resulting in smoother acceleration and a consistent idle, even under demanding conditions. Its edge-to-edge spark design concentrates energy for quicker, more reliable starts, making it ideal for racing environments. With a durable build that includes a 14mm thread, 0.75-inch reach, and gasket seat, this spark plug combines cutting-edge innovation with racing-grade reliability.
