The Wacker Neuson Air Intake Tube is a genuine OEM component designed for the G100 and G120 series portable generators. Sourced directly from Wacker Neuson, this part carries the same fit and specification as the original, ensuring a direct installation into Custom T4i, Standard T4i, Cold Weather T4i, and Hertz T4i configurations across both the G100 and G120 generator families. Whether you're servicing a unit on a construction site or restoring a generator after extended use, using the correct OEM air intake tube keeps the engine's air delivery path performing exactly as engineered.
Key Features
- Genuine OEM Airflow Integrity — Manufactured to the original duct geometry and material spec, maintaining the precise internal diameter and routing that the G100 and G120 engine requires for proper air-to-fuel metering.
- Direct-Fit Installation — Designed to connect directly to the factory air filter housing and engine intake ports on T4i-equipped G100 and G120 generators, matching original mounting points without rework.
- Broad G100 and G120 T4i Coverage — Compatible across Custom, Standard, Cold Weather, and Hertz T4i variants of both the G100 and G120 generator series, making it the right part for the widest range of these machines.
- Protects Engine Performance Under Load — A correctly sealed intake tube prevents unfiltered air from bypassing the air filter, keeping combustion clean and protecting engine internals during extended generator operation.
- Tier 4i Emissions Compliance Support — Proper intake routing is critical on T4i-certified engines; a cracked or ill-fitting tube can compromise the air management system these engines rely on to meet emissions standards.
The air intake tube channels filtered air from the air cleaner assembly into the engine's intake system. It acts as a sealed conduit that ensures only clean, measured airflow reaches the combustion chamber — a function that directly affects engine efficiency, throttle response, and fuel consumption. When the tube cracks, collapses, or develops a loose connection, unfiltered air can enter the intake path, accelerating wear on pistons, rings, and cylinder walls while causing rough running or power loss under load.
