The Wacker Neuson 5000203788 Spark Plug is a genuine OEM spark plug designed for the BPS series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications required by your machine's engine. It is confirmed to fit a wide range of BPS models including the BPS1030A, BPS1030Aw, BPS1135A, BPS1135Aw, BPS1340A, BPS1340Aw, BPS1340Aws, BPS1550A, BPS1550Aw, BPS2050A, and BPS2050Aw, as well as their EU-market variants. Replacing a worn or fouled spark plug with the correct OEM part restores clean ignition and ensures your plate compactor starts reliably and runs at full compaction power.
Key Features
- Correct OEM Ignition Spec — Manufactured to the precise heat range, thread pitch, and electrode gap required by the BPS series engine, ensuring clean, consistent spark on every pull.
- Direct Drop-In Installation — Threads directly into the existing plug seat with no adapter or modification, making replacement fast and straightforward in the field.
- Broad BPS Series Coverage — A single part number covers the BPS1030A, BPS1135A, BPS1340A, BPS1550A, and BPS2050A families, including standard and water-ballasted Aw variants and EU-spec models.
- Restores Cold-Start and Full-Load Performance — A fresh, correctly spec'd spark plug eliminates hard starting, misfiring under load, and rough idling that degrade compaction output on soil, aggregate, and paving stone applications.
- Fuel System Safety Compliance — Using the OEM-specified plug prevents pre-ignition and detonation caused by incorrect heat range, protecting the engine and fuel system from heat-related damage during sustained compaction work.
The spark plug is the component responsible for igniting the air-fuel mixture inside the engine cylinder, producing the combustion stroke that powers the machine. In a vibratory plate compactor like the BPS series, the engine runs under continuous load during operation, which places consistent demand on the spark plug's ability to fire reliably at the correct moment. When a spark plug wears out or becomes fouled with carbon deposits, the engine may become difficult to start, run rough, lose power, or consume more fuel — all of which directly impact compaction productivity on site.
