Description
Overview:
The Genuine NGK BMR7A Spark Plug (MPN 4226) is a high-quality replacement plug for a wide range of small petrol engines found in garden and construction equipment. Built with a glazed ceramic insulator, a corrosion-resistant steel shell, and a durable nickel-alloy centre electrode, it delivers a clean, reliable spark for consistent combustion. The integrated resistor helps reduce electrical interference for smoother running with modern ignition systems. Ideal for hedge trimmers, brushcutters, blowers, chainsaws and cut-off saws, it supports easy starting, steady idle and strong performance under load. Common applications include models such as the Allen Super 22 and Alpina 200 Prof. This is a Genuine Part from NGK and is sold individually to match single-plug servicing and routine maintenance tasks.
Key Features:
- Genuine NGK part for dependable quality and specification match
- Resistor type to minimise radio and electrical interference (RFI/EMI)
- Consistent ignition for easier cold starts and smooth running at high RPM
- Robust ceramic insulator and nickel-plated shell for heat and corrosion resistance
- Helps reduce fouling and misfires in typical two-stroke service
- Precision build for stable spark and efficient combustion
- Straightforward fit with common small-engine tools
- Suitable across many hedge trimmers, brushcutters, blowers, chainsaws and cut-off saws
- Cost-effective single unit for routine replacement cycles
- Backed by NGK's global ignition expertise
Typical Applications:
Routine service replacement in handheld and light machinery such as hedge trimmers, brushcutters/strimmers, leaf blowers, chainsaws and petrol cut-off saws used in landscaping, grounds maintenance, hire fleets, farming and construction. Suitable for many popular machines where a BMR7A specification is called up by the manufacturer.
