Description
Overview:
The Genuine NGK BPR4HS (MPN 7823) is a resistor spark plug designed for small petrol engines used in garden, construction, and light industrial equipment. It uses a durable nickel-alloy centre electrode with a copper core for efficient heat transfer, a white glazed ceramic insulator for strong dielectric strength, and a corrosion‐resistant steel shell. Typical applications include mowers, ride‐on lawn tractors, generators, pumps, and compact power equipment. Suitable for engines such as the 10.0HP GH400V and 2.3HP GS130, it supports reliable ignition, clean combustion, and stable running. Thread size is M14 x 1.25 with a 12.7 mm reach (1/2 in), and it takes a 20.8 mm hex (13/16 in) socket. This is a Genuine NGK part, sold individually for straightforward maintenance or like‐for‐like replacement.
Key Features:
- Genuine NGK quality for consistent ignition and dependable starting
- Resistor type helps reduce electrical interference with onboard electronics
- Nickel‐alloy, copper‐core design promotes good heat dissipation and long service life
- Robust ceramic insulator supports stable spark under varied loads and temperatures
- Corrosion‐resistant shell and sealed construction for improved durability in outdoor use
- Standard M14 x 1.25 thread and 12.7 mm reach (1/2 in) for common small engines
- Fits a 20.8 mm (13/16 in) plug socket for easy installation and removal
- Suited to a wide range of generators, lawn tractors, compact engines, and ATVs
- Supports smoother idling and cleaner combustion when matched to the correct engine spec
- Sold individually to replace a single worn or fouled plug without buying a set
Typical Applications:
Ideal for small petrol engines found on lawn tractors, walk‐behind mowers, portable generators, water pumps, pressure washers, compact construction tools, and youth ATVs. Use wherever an NGK BPR4HS is specified to maintain reliable cold starts, stable running, and consistent performance in everyday yard, site, and light commercial tasks.
