Description
Overview:
The Genuine NGK BPR4HS-10 Spark Plug (Stock No. 5024) is a resistor-type, projected-tip spark plug for small petrol engines. It uses a nickel-alloy centre and ground electrode with a copper core, a durable glazed ceramic insulator, and a plated steel shell to deliver a consistent spark and stable combustion. The -10 suffix indicates a 1.0 mm (0.040 in) factory set gap, commonly specified on compact engines. With an M14 x 1.25 thread and short 12.7 mm (1/2 in) reach, it suits lightweight plant and garden machinery such as generators, pumps, and small industrial equipment. Commonly fitted to Honda EM1500 and G200 models, and various Kubota stationary engines, it supports easy starting, smooth running, and dependable performance. This is a Genuine NGK Part, sold individually.
