Description
Overview:
The Genuine NGK CPR8EA-9 Spark Plug (MPN 2306) is a resistor-type plug engineered for dependable ignition in small to mid-size petrol engines, including motorcycles, scooters, ATVs, generators, and garden machinery. It uses a 10 mm thread with a 1.0 mm pitch, a 19 mm reach (3/4"), and a 16 mm hex (5/8") for straightforward fitting. The plug is built with a robust steel shell, a high-grade ceramic insulator, and durable nickel-alloy electrodes to deliver a consistent spark and stable heat dissipation. The integrated resistor helps reduce electrical interference with modern ignition systems and electronics. Supplied individually, it is suitable wherever the CPR8EA-9 specification is called for, supporting reliable starting, efficient combustion, and smooth running when matched to compatible engines. Factory-set gap: 0.9 mm (0.035").
