The Multiquip M1373101403 Flexible Air Filter Hose is a genuine OEM component designed for the DCA25USIXF, DCA25USI2XF, DCA25USI4CAN, and DCA25USI2 ultra-silent generator series. As a direct OEM replacement, this hose is manufactured to the exact tolerances and material specifications required for correct airflow routing on these units. Fitment has been verified against the DCA25 ultra-silent generator family, giving you confidence that M1373101403 will seat and seal correctly without modification. Keep this part on hand as a planned service item or replace it at the first sign of cracking, stiffness, or air leaks in the intake path.
Key Features
- OEM Material Integrity — Constructed to the same flexibility and heat-resistance specifications as the original, maintaining a consistent, airtight connection between the air filter housing and the intake.
- Correct Hose Routing and Geometry — Molded to the exact bend angle and end-fitting dimensions of the original, so the hose routes and clamps exactly as intended on installation.
- Verified DCA25 Series Fitment — Confirmed for DCA25USIXF, DCA25USI2XF, DCA25USI4CAN, and DCA25USI2 ultra-silent generator models.
- Protects Engine Air Supply — A sound, flexible hose ensures unfiltered air cannot bypass the filter element; a cracked or collapsed hose allows contaminants into the intake, accelerating engine wear.
- Genuine OEM Part — Sourced directly through Multiquip's authorized parts network, part number M1373101403, with no substitution or cross-brand compromise.
The flexible air filter hose connects the air filter assembly to the engine intake, channeling filtered air into the combustion system while maintaining a sealed, debris-free path. On enclosed ultra-silent generator sets like the DCA25 series, this hose must also accommodate the vibration and thermal movement common in compact enclosure environments, which is why flexibility and material durability matter. When the hose cracks, collapses, or works loose, unfiltered air enters the engine, leading to accelerated cylinder wear and potential performance loss under load.
