NGK LMAR9AI-10 Iridium Spark Plug – 93188

The NGK LMAR9AI-10 is a high-performance iridium spark plug designed to improve ignition efficiency and extend service life. It features a fine-wire 0.6mm iridium center electrode for a strong, focused spark and consistent combustion. The tapered ground electrode helps reduce quenching, and the insulator is built to withstand the heat and vibration common in modern high-revving engines.

This plug is a common upgrade over standard copper plugs for motorcycles, scooters, and lightweight sport bikes. Ideal for riders looking for better throttle response, smoother starts, and longer intervals between changes.
