Description
Overview:
The Genuine NGK Spark Plug BR8HCS-10 (MPN 1157) is a resistor-type spark plug designed to deliver consistent ignition in small petrol engines used across construction and garden machinery. Built with a copper core centre electrode and durable nickel alloy surfaces, it sheds heat efficiently and resists fouling for dependable running. The plug uses a standard M14 thread with a gasket seat for a secure seal and easy servicing. Key dimensions are: thread size 14 mm (9/16"), hex size 20.8 mm (13/16"), and reach 12.7 mm (1/2"). The "-10" code indicates a factory-set gap of 1.0 mm (0.04"). Suitable for equipment such as cut-off saws, chainsaws, brushcutters, lawn mowers, generators, plate compactors, and water pumps where an M14, 12.7 mm-reach plug is specified.
Key Features:
- Genuine NGK part for assured quality, compatibility, and long service life
- Resistor design (R) helps reduce electrical interference and protects ignition components
- Copper core electrode for efficient heat transfer and stable spark under load
- Nickel-plated shell for corrosion resistance and easier future removal
- Factory-set gap: 1.0 mm (0.04") for reliable ignition in many small engines
- Key dimensions: 14 mm (9/16") thread, 20.8 mm (13/16") hex, 12.7 mm (1/2") reach
- Robust insulator and gasket seat provide strong sealing and misfire resistance
- Suited to frequent start/stop duty common in site tools and garden equipment
- Easy to fit with a 20.8 mm (13/16") plug spanner; sold individually
- Stable performance supports smoother starts, cleaner combustion, and reduced fouling
