High-performance iridium alloy spark plug engineered for exceptional durability and enhanced ignitability. Features an ultra-fine 0.6mm wire center electrode that ensures a stable, concentrated spark, quicker engine starts, improved throttle response, and superior anti-fouling characteristics. Built with trivalent metal plating for advanced anti-corrosion and anti-seizing performance, a built-in resistor, a non-projected tip design, and a solid terminal configuration explicitly designed to resist vibration loosening.

TSO Garage Note: A medium-cold heat range (8) fine-wire iridium upgrade with a standard 19mm reach and a solid terminal nut. This is the exact solid-terminal equivalent to stock #5044 (the standard BR8EIX). It is the ultimate anti-fouling, high-performance upgrade for applications that endure extreme high-frequency vibration—such as two-stroke personal watercraft (PWCs), snowmobiles, and big-bore dirt bikes—where standard removable terminal nuts are prone to backing off and causing ignition issues.
