Wacker Neuson 5000158498 Spark Plug

The Wacker Neuson Spark Plug is a genuine OEM component designed for a wide range of Wacker Neuson gasoline-powered equipment, including BFS floor saws, CT and CRT concrete trowels, GP and GPS portable generators, BPU vibratory plate compactors, VP single-direction vibratory plates, WP vibratory plates, RD tandem rollers, and PDT/PDI diaphragm trash pumps. As a direct OEM replacement, this spark plug is built to the exact specifications of the original part — ensuring correct heat range, electrode gap, and thread engagement for every application it covers. Whether you are servicing a CT48 ride-on trowel, a GP6600A generator, or a BPU 3050A compactor, part number is the correct factory-specified plug. Keep a spare on hand to minimize unplanned service interruptions across your fleet.

Key Features

• OEM Heat Range and Electrode Spec — Manufactured to the exact heat range and electrode gap required by Wacker Neuson gasoline engines, ensuring complete combustion and proper ignition timing across all covered models.
• Drop-In Thread and Seat Fit — Matches the original plug's thread pitch, reach, and seat type for a straightforward swap with standard hand tools — no adapters or modifications to the cylinder head.
• Broad Multi-Equipment Fitment — A single part number covers BFS floor saws, CT/CRT concrete trowels, GP/GPS generators, BPU/VP/WP vibratory plates, RD tandem rollers, and PDT/PDI diaphragm pumps, making it an efficient stock item for mixed Wacker Neuson fleets.
• Consistent Cold-Start and Full-Load Performance — A worn or fouled spark plug causes hard starts, misfires, and loss of power under load. Installing a fresh 5000158498 restores reliable ignition from the first pull through peak operating demand.
• Fuel System Safety Compliance — A correctly gapped, OEM-spec plug prevents pre-ignition and engine knock, protecting the piston crown and combustion chamber from heat damage during sustained operation.
• Genuine Wacker Neuson Part — Supplied as an authorized OEM component, this spark plug carries the correct part number validation for service records and equipment maintenance documentation.

A spark plug is the ignition source for a gasoline engine — it delivers a precisely timed electrical spark that ignites the air-fuel mixture in the combustion chamber, driving the piston and producing power. The plug must operate within a specific heat range to burn off combustion deposits without overheating; a plug that runs too cool will foul with carbon, while one that runs too hot risks pre-ignition damage. Over time, electrode wear increases the firing voltage required, leading to misfires, rough idle, reduced power output, and difficult starting — symptoms that a simple plug replacement with the correct OEM part will resolve.
