The Wacker Neuson Spark Plug is a genuine OEM Spark Plug designed for the RD12-90 Tandem Roller and CRT36-25 Ride-on Trowel series. As a factory-sourced component, it is manufactured to the exact specifications required by Wacker Neuson equipment, ensuring consistent ignition performance across every application it covers. This part fits both solid ROPS and foldable ROPS configurations of the RD12-90, as well as standard and Wheel Kit-equipped variants of the CRT36-25.
Key Features
- OEM Ignition Spec: — Manufactured to Wacker Neuson's exact heat range and electrode gap requirements, delivering consistent spark energy and complete combustion in the engine.
- Drop-In Installation: — Engineered to the correct thread pitch and reach for a straight swap into the cylinder head — no re-gapping or thread chasing needed.
- Broad Wacker Neuson Fitment: — Covers multiple RD12-90 Tandem Roller configurations and CRT36-25 Ride-on Trowel variants, including Wheel Kit-equipped models.
- Reliable Cold Starts and Smooth Running: — A fresh, correctly spec'd Spark Plug restores reliable starting, smooth idle, and full engine power — worn plugs cause misfires, hard starts, and increased fuel consumption.
- Genuine Part Assurance: — Sourced directly from Wacker Neuson, part number 5000215278 carries the same quality verification as any component fitted at the factory.
A Spark Plug ignites the air-fuel mixture inside the engine's combustion chamber, triggering the controlled explosion that drives the piston and generates power. Without a properly functioning plug, combustion becomes inconsistent — leading to rough running, failed starts, elevated fuel use, and potential damage to the engine over time. Replacing a worn or fouled Spark Plug is one of the most impactful routine maintenance steps you can take to keep a compact roller or ride-on trowel running at full output.
