The Wacker Neuson 5000408439 is a genuine OEM Spark Plug designed for BPS-series vibratory plate compactors and MP-series plate compactors, including the BPS1550Gw-c, BPS2050Gw-c, MP12, MP15, MP20, and MP70. As a factory-sourced component, the 5000408439 meets Wacker Neuson's original ignition specifications, ensuring the engine fires correctly under the continuous load demands of compaction work. Verified fitment covers both CE and CN variants of the BPS1550Gw-c and BPS2050Gw-c, along with multiple production runs of the MP12 and MP15 — check your model and machine number before ordering to confirm compatibility.
Key Features
- Correct Ignition Heat Range: — Matched to the engine's thermal load, this OEM spark plug maintains the proper heat range to prevent fouling during sustained plate compactor operation.
- Genuine OEM Sourcing: — Supplied directly from Wacker Neuson, the 5000408439 meets the original ignition output and electrode gap specifications for these engine families.
- Drop-In Replacement: — Threads directly into the cylinder head with the same reach and seat as the original, allowing a straightforward swap during routine service intervals.
- Broad Model Coverage: — A single part number covers the BPS1550Gw-c, BPS2050Gw-c, MP12, MP15, MP20, and MP70 vibratory plate compactor lines, including CE and CN market variants.
- Clean, Consistent Starts: — A fresh spark plug restores reliable cold and hot starts, stable idle, and full power delivery — deteriorated plugs cause misfires, hard starting, and lost compaction output.
A spark plug ignites the air-fuel mixture inside the engine cylinder, converting fuel into the power that drives the compactor's vibration mechanism. In plate compactors, the engine runs under near-constant throttle load, which causes spark plugs to wear faster than in lighter-duty applications — a degraded electrode gap or fouled insulator leads to weak sparks, rough running, increased fuel consumption, and eventually a no-start condition. Replacing the spark plug at the manufacturer's recommended interval keeps ignition timing accurate and the engine performing at the output level the compactor plate requires.
