The Genuine BR9EG NGK Spark Plug (Stock No. 3230) is a high-quality ignition component for small petrol engines used in construction machinery and garden equipment. Built by NGK, it combines a durable steel shell with anti-corrosion plating, a robust ceramic insulator, and a copper-cored, nickel-alloy centre electrode to deliver a consistent spark. With a 14 mm thread and 1.25 mm pitch, it suits engines that specify this size, providing reliable starting and steady running under load. The resistor design helps suppress electrical interference with tools or onboard electronics. Suitable for many two-stroke and four-stroke applications where a BR9EG is specified, it supports dependable performance and straightforward maintenance using a standard plug spanner.

– Resistor type to reduce radio frequency interference and electrical noise
– Copper core with nickel-alloy electrode for reliable ignition and heat dissipation
– Strong ceramic insulator resists fouling and supports stable combustion
– Consistent cold starts and smooth running when serviced to the engine maker’s gap specification
– Corrosion-resistant shell for longer service life in tough site and outdoor conditions
– Suited to both two-stroke and four-stroke engines that call for BR9EG
– Straightforward replacement during routine servicing to help maintain fuel efficiency

Typical Applications:
Used in small petrol engines found on generators, plate compactors, cut-off saws, pressure washers, brushcutters, hedge trimmers, and ride-on or walk-behind mowers. Ideal for workshop servicing and field repairs where dependable starting and stable idling are required, provided the equipment specifies an NGK BR9EG with M14 1.25 thread.
