The Wacker Neuson Spark Plug is a genuine OEM Spark Plug designed for a wide range of Wacker Neuson equipment, including the RD12A-90 Tandem Roller series, CRT36-26A and CRTv36-26A Trowels, the BFS 2020AS Saw, GS12Ai, and the GPS9700A. As a factory-sourced component, this Spark Plug is built to the exact specification of the original part it replaces, ensuring your engine fires cleanly and runs at its best. Wacker Neuson genuine OEM parts are manufactured to the same standards as the components installed at the factory, so you can install this Spark Plug with full confidence in its fit and function. Whether you are performing scheduled maintenance or addressing an ignition issue, part number is the correct choice for these machines.
Key Features
- Correct Electrode Gap and Heat Range — Manufactured to the exact ignition specification of the original, ensuring reliable spark timing and combustion efficiency across all compatible engines.
- Direct Drop-In Replacement — Matches the original thread pitch, reach, and hex size for a straightforward installation with no modification to the plug socket or ignition lead.
- Broad Wacker Neuson Fitment — Compatible with the RD12A-90 Tandem Roller series, CRT36-26A and CRTv36-26A Trowels, BFS 2020AS Saw, GS12Ai, and GPS9700A machines.
- Clean Ignition, Consistent Power — A correctly functioning Spark Plug sustains proper combustion; a worn or fouled plug leads to hard starting, rough idling, and reduced engine output.
- Ignition System Safety — A correctly gapped, OEM-spec Spark Plug reduces the risk of misfires and unburned fuel accumulation in the combustion chamber, supporting safe, controlled engine operation.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network and carries part number 5000226565 for accurate identification and reordering.
A Spark Plug is responsible for igniting the air-fuel mixture inside an engine's combustion chamber. Each time the engine cycles, the plug fires a small electrical spark at a precise moment, triggering combustion that drives the piston and powers the machine. When a Spark Plug wears out, develops deposit buildup, or the electrode gap widens beyond specification, ignition becomes inconsistent — leading to hard starts, rough running, loss of power, and increased fuel consumption. Replacing the plug at the manufacturer's recommended service intervals keeps the engine performing as intended and prevents secondary wear caused by misfires.
