Description
Overview:
The Genuine NGK BPR6EF Spark Plug (MPN 4665) is a high-quality ignition component for petrol engines used in garden and construction equipment. It uses a nickel-alloy centre electrode, a durable ceramic insulator, and a corrosion-resistant steel shell to deliver consistent ignition under everyday working conditions. As an NGK resistor-type plug, it helps reduce electrical interference while supporting stable running and clean combustion. With a 14 mm thread and compact form, it suits many small to medium engines found in lawnmowers, ride-on mowers, generators, pressure washers, pumps, compactors, and mixers. This is a Genuine NGK part and is sold individually, making it a straightforward like-for-like replacement for routine servicing or to resolve hard starting and misfire issues.
Key Features:
- Genuine NGK part for assured quality and fit (MPN 4665), sold individually.
- Reliable ignition for easier starts, smoother idling, and steady performance across typical small petrol engines.
- Resistor design helps limit radio frequency interference with nearby electronics.
- Durable nickel-alloy centre electrode and robust ceramic insulator support long service life.
- Standard 14 mm thread size with 1.25 mm pitch (approx. 0.049") for broad compatibility.
- Reach: 17.5 mm (11/16") for correct seating depth in suitable cylinder heads.
- Hex size: 20.8 mm (13/16") for easy fitting with common plug sockets.
- Built to handle frequent stop/start use and variable loads typical of outdoor power equipment and site machinery.
- Straightforward replacement; check and set the gap to the engine manufacturer's specification.
Typical Applications:
Suitable for many petrol-powered tools and machines such as lawnmowers, ride-on mowers, generators, pressure washers, water pumps, plate compactors, and cement mixers. Often chosen during scheduled maintenance to restore clean ignition, address poor starting, or improve fuel efficiency in small engines used by homeowners, landscapers, and trades.
Also known as:
Often referred to as an ignition electrode, engine ignition element, high-tension plug, 14 mm resistor type, combustion chamber ignition unit, or petrol engine ignition component. These terms describe the same function of delivering a controlled spark to ignite the air-fuel mixture within the cylinder.
