The Multiquip M1373101103 Flexible Air Filter Hose is a genuine OEM component designed for DCA45USI4CAN and DCA45USI2 ultra-silent diesel generators. As a factory-sourced part, it meets the original design specifications set for these machines, ensuring a correct and secure connection between the air filter housing and the intake system. This part is confirmed to fit the DCA45USI4CAN (including the Canadian FR variant) and DCA45USI2 models, making it a straightforward service replacement for technicians maintaining these units.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications for the DCA45 ultra-silent generator series, ensuring the hose maintains correct airflow geometry and seal integrity.
- Direct-Connect Fitment — Routes and connects exactly as the original, with matching end diameters and hose length to seat flush against the air filter housing and intake port without trimming or adapting.
- Confirmed Compatibility — Fits DCA45USI4CAN, DCA45USI4CAN (FR), and DCA45USI2 ultra-silent diesel generator models.
- Sustained Intake Performance — A properly seated air filter hose maintains a sealed, unobstructed air path to the engine; a cracked or loose hose allows unfiltered air and debris into the intake, accelerating engine wear.
- Fuel System Protection — Maintaining a sealed air intake path supports correct air-to-fuel ratio, protecting injector and combustion chamber condition over long generator run cycles.
The flexible air filter hose connects the air filter assembly to the engine intake, channeling clean, filtered air into the combustion system. Its flexible construction allows it to absorb vibration and accommodate the slight positional movement common in generator enclosures without cracking or losing its seal. When this hose deteriorates, splits, or pulls loose at either end, unfiltered air bypasses the filter element entirely, introducing dust and contaminants directly into the engine — leading to accelerated wear on cylinders, rings, and injectors over time.
