Description
Overview:
The Genuine NGK CMR7H Spark Plug (MPN 3066) is a high-quality resistor spark plug for modern two‐stroke and four‐stroke small engines. Built with a durable steel shell and a robust ceramic insulator, it delivers a strong, consistent spark to keep equipment starting easily and running smoothly. Designed for handheld and backpack machines, it is well suited to chainsaws, hedge trimmers, brushcutters and blowers, including popular models such as Jet DS 2500 and 130BT. Precision manufacturing from NGK helps maintain reliable ignition under varied loads and temperatures, supporting clean combustion and stable idle. This plug is sold individually and is a Genuine Part, giving assured compatibility and performance in routine servicing or as a direct replacement during a tune‐up.
Key Features:
- Genuine NGK component for assured quality and compatibility
- Resistor type to reduce electrical interference with ignition systems
- Durable steel shell and glazed ceramic insulator for long service life
- Consistent spark for easy starting, smooth running and stable idle
- Reliable performance across frequent stop‐start use and varying loads
- Clean combustion support helps minimise fouling in small engines
- Precision fit for compatible tools, reducing the risk of cross‐threading
- Straightforward like‐for‐like replacement; sold individually
- Suitable for professional and DIY maintenance schedules
Typical Applications:
Used during routine servicing or troubleshooting misfires on chainsaws, hedge trimmers, brushcutters, multi‐tools and backpack blowers. Ideal where reliable cold starting and consistent throttle response are important, such as landscaping, arborist work, grounds maintenance, and property care. Fits many popular small engines used by contractors and homeowners.
