The Multiquip M4310501303 is a genuine OEM Inter Cooler Hose designed for DCA220SSJ, DCA220SSJU, and DCA180SSJU ultra-silent diesel generator sets. Sourced directly from Multiquip, this hose meets the exact material and dimensional specifications of the original component. It is a direct-fit replacement for the factory inter cooler hose position on these DCA series units, requiring no modification to connect correctly. Keeping this hose in sound condition is essential to maintaining proper charge air flow and sustained generator output on job-critical power applications.
Key Features
- OEM-Grade Hose Construction — Manufactured to Multiquip's original material specification, delivering the correct wall thickness, flexibility, and heat resistance for turbocharged diesel inter cooler service.
- Exact-Fit Replacement — Engineered to the original routing geometry and end diameters of the M4310501303 position, so the hose seats and clamps without adjustment.
- Confirmed Fitment for DCA Series Generators — Compatible with DCA220SSJ, DCA220SSJU, and DCA180SSJU ultra-silent generator models.
- Charge Air Integrity — A sound inter cooler hose maintains the pressurized air path between the turbocharger and engine intake, supporting full rated power output and efficient fuel combustion.
- Prevents Boost Leaks Before They Start — Cracked or collapsed inter cooler hoses cause boost loss, elevated exhaust temperatures, and reduced generator capacity; replacing with a genuine OEM hose restores the sealed charge air circuit.
The inter cooler hose carries compressed, heated air from the turbocharger outlet to the inter cooler, and then routes the cooled, denser charge air onward to the engine intake manifold. By lowering the temperature of the compressed intake air, the inter cooler allows the engine to burn fuel more efficiently and produce its full rated output. When this hose cracks, collapses, or blows off its fittings, the pressurized air path is broken, causing a noticeable drop in power output, increased fuel consumption, and potential thermal stress on the engine — making prompt replacement critical for any generator operating under load.
