The Genuine NGK Spark Plug CR8EHIX-9 is a high-quality ignition component for small petrol engines used in construction and garden machinery. It combines a robust steel shell with a white ceramic insulator and a fine-wire centre electrode design to deliver reliable, efficient combustion. With a thread size of M10 1.0, a 19 mm (0.75 inches) thread reach, and a 16 mm he(5/8 inch) for straightforward fitting, it suits compact engines where space is limited. The “R” in the code denotes an internal resistor to reduce radio-frequency interference, helping stable ignition under load. The “-9” suffiindicates a factory gap of 0.9 mm (0.035 inches). As a Genuine NGK part (OEM No. CR8EHIX-9), it offers dependable performance for generators, pumps, plate compactors, pressure washers, lawn tractors, and brushcutters.
