The Wacker Neuson Plug Cap is a genuine OEM component designed for the BFS 2020AS floor saw. As a factory-sourced part, it meets the exact specifications Wacker Neuson requires for proper ignition circuit performance on the BFS 2020AS. Sourcing the correct plug cap by part number ensures a direct, trouble-free installation with no guesswork on fitment or compatibility.
Key Features
- OEM Ignition Spec Compliance — Manufactured to the exact resistance and terminal spec required by the BFS 2020AS ignition system, ensuring consistent spark delivery to the plug.
- Direct Terminal Fit — Engineered to seat flush on the spark plug terminal and connect cleanly to the high-tension lead, just as the original was installed at the factory.
- BFS 2020AS Compatibility — Verified fitment for the Wacker Neuson BFS 2020AS floor saw; cross-reference part number 394132020 before ordering to confirm your machine's configuration.
- Protects Ignition Wire Integrity — A properly fitted plug cap seals out moisture and debris at the plug connection, protecting the high-tension lead from premature degradation.
- Supports Clean, Reliable Starts — A worn or cracked plug cap causes misfires, hard starting, and erratic cutting power on saw-dependent concrete work — replacing it restores consistent ignition performance.
The plug cap connects the high-tension ignition lead to the spark plug, completing the ignition circuit that fires the engine. It forms a secure, insulated seal over the plug terminal to transfer the high-voltage pulse cleanly while keeping moisture and contaminants out. When a plug cap cracks, loosens, or deteriorates internally, the result is a weak or intermittent spark — leading to hard starts, misfires, or a complete loss of ignition that stops the saw mid-cut.
