Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original exhaust specification, ensuring correct mesh sizing and heat tolerance for the Honda engines used across the GA and GAW series.
- Drop-In Exhaust Fit — Mounts directly to the exhaust outlet of compatible models with no rework to the exhaust system required.
- Broad Series Coverage — Confirmed fitment across GAW180HE, GAW180HEA, GAW180HE1, GAC6HR, GAC6HRS, GAC3.6HR, GA6HR, GA3.6HR, GA3.6HA, GA3.6HZ, GA6HEB, and GA6HB equipment.
- Emissions and Site Compliance — A properly functioning spark arrester is required on many jobsites and in fire-risk environments; using the correct OEM part helps meet those requirements with confidence.
- Exhaust Integrity Maintained — A worn or missing arrester allows hot carbon particles to exit the exhaust stream; replacing it with part 18355ZB4630 restores safe, clean exhaust operation.
A spark arrester is a screen or baffle fitted to the exhaust outlet of a gasoline engine that captures and extinguishes hot carbon particles before they can exit the exhaust stream. On generators and engine-driven welders like the Multiquip GA and GAW series, this component plays a critical role in preventing ignition of nearby combustible materials — particularly important when equipment is operating on jobsites near dry vegetation, fuel storage, or enclosed structures. When a spark arrester becomes clogged with carbon deposits it can restrict exhaust flow and cause the engine to run hot; when it deteriorates or goes missing entirely, it creates a fire hazard and may violate site safety regulations.
