Wacker Neuson 5200010127 Rear Inlet Duct, G320, Black 112007

The Wacker Neuson Rear Inlet Duct, G320, Black 112007 is a genuine OEM component designed for the G320 portable generator series. This duct is sourced directly from Wacker Neuson, ensuring it meets the exact fit and material specifications required for the G320 platform across Standard, Cold Weather, Custom, and Mobile configurations — including T4, T4i, and Tier 4 Final emissions variants. Whether you're servicing a standard unit or a Transport Canada-compliant mobile generator, part number is the correct OEM replacement. Keeping the airflow path intact with the right duct supports proper cooling performance and helps your generator run at full output under load.

Key Features

• OEM Air Channel Integrity — Molded to exact dimensional tolerances, this duct maintains the engineered airflow path that Wacker Neuson designed into the G320 cooling system — no gaps, no air bypass.
• Direct-Fit Installation — Mounts to the factory rear inlet location on the G320 enclosure using the original attachment points, making swap-out straightforward during routine service or after damage.
• Broad G320 Series Coverage — Fits Standard, Cold Weather, Custom, and Mobile G320 configurations, including T4, T4i, and Tier 4 Final variants, as well as Transport Canada-spec units.
• Correct OEM Coloring (Black 112007) — Matched to the factory black finish specified for G320 enclosures, so the replacement blends seamlessly with the existing generator housing.
• Protects Generator Cooling Performance — A cracked, missing, or ill-fitting rear inlet duct can allow hot air recirculation or restrict fresh air intake, leading to elevated operating temperatures and reduced output capacity.

The rear inlet duct channels ambient air into the G320 generator's cooling system through the back of the enclosure. By directing a controlled volume of fresh air across the engine and alternator, it plays a key role in keeping operating temperatures within the designed range. When this duct is cracked, deformed, or missing, uncontrolled air movement inside the enclosure can allow exhaust heat to recirculate back through the intake path — causing the generator to run hotter than intended, which can trigger thermal protection shutdowns or accelerate wear on internal components over time.
