Product Description

The NGK 94124 Laser Iridium Spark Plug (also known by service code ILKAR7L11) is engineered to provide reliable ignition performance and long life in modern high-efficiency petrol engines. Its laser-welded iridium center electrode delivers superior ignitability and durability, while the platinum pad on the ground electrode enhances wear resistance and helps maintain consistent gap over time. The solid copper core promotes effective heat dissipation, and the built-in resistor reduces electrical noise to support smooth combustion and engine operation.

This spark plug is a confirmed OEM or direct replacement fitment for a wide range of Mazda vehicles including the Mazda 3, Mazda 6, CX-3, CX-30, CX-5, and CX-50 across various model years and petrol engine sizes. It is ideal for maintenance, tune-ups, or replacement during scheduled service intervals. Always consult your vehicle's service manual for the correct torque and gap settings when installing spark plugs.
