Description
Overview:
The NGK TR6AP-13 Spark Plug (MPN 5809) is a genuine OEM part designed to deliver reliable ignition in petrol engines used across construction and garden machinery. Built with a durable, corrosion‐resistant metal shell and an alumina ceramic insulator, it uses a copper‐core centre electrode for effective heat transfer and a consistent spark. The "R" code denotes a resistor type to reduce electrical interference with onboard electronics. Key dimensions include a 16 mm hex, M14 x 1.25 thread, and 17.5 mm (0.69 in) thread length for correct reach. It is suited to small plant and garden tools such as mowers, generators, pumps, plate compactors, and pressure washers that specify TR6AP-13. Genuine NGK build quality supports dependable starting, smooth running, and stable idle in everyday and professional use.
