Wacker Neuson 5000156554 Spark Plug

The Wacker Neuson Spark Plug is a genuine OEM component designed for a broad range of Wacker Neuson gasoline-powered equipment, including CT36 and CT48 concrete power trowels, VP and WP series vibratory plate compactors, PT2 and PT3 centrifugal trash pumps, PDT and PG series pumps, GP2600, GP4000, GPi3200, GPi4300, and GPSi series portable generators, and BFS series floor saws. Sourced directly from Wacker Neuson, this spark plug meets the exact ignition specifications of every covered machine, ensuring correct heat range, thread pitch, and electrode gap right out of the box. Whether you are servicing a concrete finishing trowel on a slab pour or maintaining a vibratory plate on a compaction crew, this is the correct OEM ignition part for the job. Keep a spare on hand so routine tune-ups never slow your operation.

Key Features

• Correct Ignition Specification — Manufactured to the exact heat range and electrode gap required by Wacker Neuson gasoline engines, so combustion efficiency is maintained from first start to last shutdown.
• Genuine OEM Part — Supplied by Wacker Neuson as original equipment, meaning it carries the same ignition characteristics as the plug installed at the factory — no guesswork on compatibility.
• Broad Multi-Machine Fitment — A single part number covers CT36 and CT48 trowels, VP and WP vibratory plates, PT2/PT3 trash pumps, PDT/PG diaphragm and dewatering pumps, GP/GPi/GPSi generators, and BFS floor saws, making it an efficient stocking item for mixed fleets.
• Direct Drop-In Replacement — Matches the thread size, reach, and connector type of the original plug, so installation requires only a spark plug wrench — no adapters or modifications to the plug boot or ignition wire.
• Engine Performance Protection — A fresh, properly gapped spark plug delivers a strong, consistent spark that supports clean combustion, smooth idle, and full power output. A fouled or worn plug causes hard starting, misfires, increased fuel consumption, and uneven engine behavior.
• Fuel System Safety Relevance — A correctly functioning spark plug prevents raw fuel from passing unburned into the exhaust, reducing the risk of backfire or carbon buildup in gasoline-powered equipment operating in enclosed or partially enclosed environments.

A spark plug is the ignition source for a gasoline engine — it delivers a precisely timed high-voltage spark that ignites the compressed air-fuel mixture inside the combustion chamber. That single spark event drives the piston and powers everything from the centrifugal plate to the trowel blades to the pump impeller. When a spark plug wears out, the electrode gap widens, the insulator fouls with carbon, or the plug simply fails to fire consistently — the result is hard starts, rough running, loss of power, and higher fuel consumption. Replacing the spark plug at the manufacturer-recommended service interval is one of the simplest and most cost-effective maintenance steps for any gasoline-powered piece of equipment.
