Description
Overview:
The NGK AB-6 Spark Plug is a robust, small‐engine plug designed to restore clean ignition and steady running. It uses a copper‐core centre electrode within a plated steel shell and a high‐strength ceramic insulator to manage heat and deliver a consistent spark. With an 18 mm thread diameter (1.8 cm), it suits engines that specify larger plug threads often found in older or heavy‐duty garden and construction equipment. Typical applications include mowers, generators, pumps, plate compactors, and mixers. The AB‐6 designation helps identify the correct heat range and form for many small petrol engines. Manufacturer reference 2910 is commonly used for this plug. If replacing a tired or fouled plug, the AB‐6 is a straightforward way to improve starting, throttle response, and fuel efficiency.
Key Features:
- 18 mm thread diameter (1.8 cm) for engines requiring large-thread plugs
- Copper core for strong conductivity and efficient heat transfer
- Plated steel shell for corrosion resistance in damp or dusty worksites
- Durable ceramic insulator for reliable high‐voltage performance
- Stable ignition to aid cold starts, idling, and smooth acceleration
- Helps recover power and fuel economy when replacing worn plugs
- Suitable for many 2‐stroke and 4‐stroke small petrol engines
- Simple to fit with a standard spark plug spanner; check gap to engine spec
- Widely used across garden and construction machinery for dependable service
- NGK build quality for long service intervals under varied loads
Typical Applications:
Used in small petrol engines powering lawn mowers, scarifiers, rotavators, generators, water pumps, plate compactors, cement mixers, and similar equipment. Well suited to older or industrial engines that specify an 18 mm thread plug. Ideal for routine servicing, seasonal recommissioning, or solving hard‐starting and misfire issues caused by fouled or eroded plugs.
