The Honda 30700-ZA0-802 Noise Suppressor Cap Assembly is a genuine OEM component designed for ES6500 and EX5500 generators and GX360 horizontal shaft engines. As a factory-original part, it is manufactured to the same specification as the unit your equipment left the factory with, ensuring a correct, trouble-free installation. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this assembly may not apply to every production run.
Key Features
- Genuine OEM Ignition Quality — factory-original Honda construction ensures the cap seats and seals correctly on the spark plug terminal, maintaining the suppression performance the ignition system depends on
- Direct OEM Replacement — engineered to drop in as a like-for-like swap on ES6500 and EX5500 generators and GX360 engines without alteration
- Broad Fitment Across Two Equipment Classes — covers ES6500 and EX5500 generators as well as GX360 horizontal shaft engines; verify your serial number against the fitment table to confirm the correct assembly for your unit
- Restored Ignition Integrity — a cracked, corroded, or poorly fitting suppressor cap allows voltage to leak, causing misfires, hard starting, and interference with nearby electronics; this assembly restores a clean, contained spark path
The Noise Suppressor Cap Assembly is the boot-and-terminal unit that connects the spark plug wire to the spark plug itself. It serves a dual purpose: it delivers the high-voltage pulse from the ignition coil to the plug's electrode while simultaneously suppressing the electromagnetic interference that firing produces — interference that can disrupt onboard electronics, nearby sensors, or sensitive equipment running alongside the generator or engine. When the cap cracks, corrodes, or loses its internal contact, the result is a weak or intermittent spark, leading to misfires, rough running, or a refusal to start.
