The Wacker Neuson Spark Plug Bpr2Es Honda is a genuine OEM ignition component designed for Honda-powered Wacker Neuson equipment including the RD12A-90 Tandem Roller series, BFS 2020AS Floor Saw, RD11A and RD11AEC Hydrostatic Double Drum Vibratory Rollers, and the GS12Ai Portable Generator. Sourced directly from Wacker Neuson, part matches the exact specification of the original plug installed at the factory, ensuring a correct fit with no guesswork. This genuine OEM spark plug delivers the consistent ignition performance that Honda engines in these machines depend on for reliable starts and smooth power delivery across demanding job conditions.
Key Features
- OEM-Grade Electrode Material — Genuine Wacker Neuson part 5000118791 uses the correct electrode alloy and gap spec for Honda engines, maintaining proper ignition timing and combustion efficiency.
- Drop-In Thread and Heat Range Match — Threaded to the exact pitch, reach, and heat range of the original plug, so it seats and torques correctly in the Honda cylinder head without modification.
- Broad Fitment Across Multiple Machine Families — Compatible with RD12A-90 Tandem Rollers, RD11A and RD11AEC Hydrostatic Double Drum Vibratory Rollers, the BFS 2020AS Floor Saw, and the GS12Ai Portable Generator.
- Clean, Consistent Ignition — A fresh, correctly specified plug restores full spark energy, supporting strong starts, stable idle, and peak engine output. A worn or fouled plug causes hard starts, misfires, and increased fuel consumption.
- Fuel System Safety Compliance — Using the correct heat-range plug prevents pre-ignition and detonation, which can cause engine damage and create unsafe operating conditions in fuel-system-adjacent components.
A spark plug ignites the compressed air-fuel mixture inside the engine cylinder, converting fuel energy into the mechanical power that drives the machine. In Honda-powered Wacker Neuson equipment, the plug must maintain a precise heat range and electrode gap to fire reliably under varying loads and temperatures. When a spark plug wears out or fouls, the result is hard starting, rough running, increased emissions, and accelerated wear on the engine — making timely replacement essential to keeping these machines performing at their best.
