Key Features

• Genuine OEM Ignition Integrity — Factory-sourced from Multiquip, this cap assembly maintains the correct suppression rating and terminal contact spec required by Honda-engine ignition systems across all compatible models.
• Direct Plug-In Replacement — Designed to seat and lock onto the spark plug boot connection exactly as the original, requiring no modification to the ignition lead or plug terminal.
• Exceptionally Wide Fitment Coverage — Compatible with MVC plate compactors, GA portable generators, WM and EM mortar mixers, QP pumps, MC and EC concrete mixers, flat saws, masonry saws, walk-behind trowels, and more — all sharing the Honda small-engine platform.
• Suppresses Ignition Interference — A functioning noise suppressor cap prevents electromagnetic interference from degrading engine control signals, sensor readings, and any onboard electronics operating near the ignition system.
• Protects Spark Plug Boot and Terminal — The cap assembly shields the spark plug connection from moisture, debris, and vibration — common failure accelerators on compaction and mixing equipment operating in demanding site conditions.

The noise suppressor cap assembly is the protective cover and interference-suppression component that fits over the spark plug on small gasoline engines. It serves two roles: it physically seals the spark plug terminal against moisture and contamination, and it contains a resistor element that dampens the electromagnetic pulse generated each time the ignition fires. When this cap cracks, corrodes, or loses its internal resistance, the engine may misfire, run rough, or fail to start — and nearby electronic components such as hour meters, tachometers, or control modules can experience interference. Replacing a worn or damaged cap restores a clean, reliable ignition signal and protects the broader electrical system on the machine.
