Description
Overview:
The NGK PMR7A Spark Plug is a genuine ignition component for small petrol engines used in garden and light construction equipment. Built with a steel shell and a high-grade ceramic insulator, it uses a projected-tip design to deliver a clean, reliable spark for efficient combustion. Typical NGK nickel-alloy electrodes offer stable performance and long service life in varied operating conditions. The plug measures 85 x 24 x 22 mm (3.35 x 0.94 x 0.87 inches), making it compact enough for tight engine bays. Marked with OEM code PMR7A and NGK Manufacturer Part Number (MPN) 4259, it supports dependable starting, smooth running, and consistent throttle response. Suitable for lawnmowers, brushcutters, hedge trimmers, compact generators, pressure washers, and other small plant or site tools using compatible ignition systems.
Key Features:
