Description
Overview:
The NGK D6HA is a genuine spark plug (Stock No. 6512) for small petrol engines used in construction and garden machinery. Built with a nickel-alloy centre electrode and copper core for steady heat transfer, it features a robust steel shell with anti-corrosion plating and a durable ceramic insulator. The plug has a 12.7 mm reach (1/2"), an M12 x 1.25 thread, an 18 mm hex (11/16") for standard sockets, and a factory-set gap of 0.7 mm (0.028"). Designed to ignite the air-fuel mixture cleanly, it supports reliable cold starting, smooth idling, and efficient running. Suitable for equipment such as generators, compactors, pumps, lawnmowers, and brushcutters, this NGK D6HA is sold individually for straightforward maintenance and replacement.
