Description
Overview:
The NGK BPMR4A (Stock No. 6028) is a genuine small-engine spark plug designed for reliable ignition in garden and light construction machinery. Built with a white ceramic insulator and a plated steel shell for corrosion resistance, it uses a durable nickel-alloy centre electrode and an internal resistor to help reduce electrical interference. With a 14 mm x 1.25 thread, 9.5 mm thread reach (3/8 inch), and 19 mm hex size (3/4 inch), it fits many compact petrol engines found in lawn mowers, trimmers, and small plant equipment. Common applications include models such as the Flymo GT500 and Honda HRB423. Supplied singly, it is a straightforward like-for-like replacement to maintain smooth starting, clean running, and consistent performance.
Key Features:
- 14 mm x 1.25 thread, short 9.5 mm reach (3/8 inch) for compact cylinder heads
- 19 mm hex size (3/4 inch) for easy fitting with a standard socket
- Resistor type to minimise radio-frequency interference on modern equipment
- Durable nickel-alloy electrode and robust ceramic insulator for long service life
- Corrosion-resistant shell to withstand damp and dirty working conditions
- Consistent ignition for easier cold starts and steady idle
- Suitable for many small 2‐stroke and 4‐stroke engines in garden and site machinery
- Genuine NGK specification for dependable performance
- Simple, quick replacement to reduce downtime
- Sold individually
Typical Applications:
Used during routine servicing of petrol lawn mowers, strimmers/line trimmers, brushcutters, hedge trimmers, small tillers, compact generators, and similar small-engine tools. Ideal where a short-reach M14 plug is specified, helping maintain efficient combustion, reliable starting, and stable running in both domestic and professional equipment.
