The Multiquip C3311400003 is a genuine OEM Inter Cooler Pipe designed for the DCA400SSI4F series super-silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3B, DCA400SSI4F3PD, and DCA400SSI4F/4F3/4F3PB configurations. As a genuine Multiquip OEM component, it is manufactured to the same specification as the original part, ensuring a correct, trouble-free installation. This pipe plays a critical role in the charge-air cooling circuit of these high-output generator sets, and using the correct replacement helps maintain consistent performance and thermal efficiency. Verify your generator model code before ordering to confirm compatibility with this part.
Key Features
- Genuine OEM Construction — Manufactured to the original engineering specification for the DCA400SSI4F series, ensuring correct dimensions, wall thickness, and connection geometry throughout the charge-air circuit.
- Direct-Fit Replacement — Engineered to connect directly to the existing charge-air routing without modification to hose clamps, mounting brackets, or adjacent components.
- Broad DCA400SSI4F Series Coverage — Compatible across DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3B, DCA400SSI4F3PD, and DCA400SSI4F/4F3/4F3PB generator configurations.
- Sustained Charge-Air Efficiency — A properly seated inter cooler pipe maintains airflow integrity between the turbocharger and intercooler; a cracked or leaking pipe causes boost pressure loss, higher exhaust temperatures, and reduced generator output.
- Sourced Through an Authorized Multiquip Distributor — Sold by DHS Equipment, an authorized Multiquip parts source, so the part number, fitment data, and OEM designation are verified at the point of sale.
The inter cooler pipe carries compressed, heat-saturated air from the turbocharger outlet to the intercooler (charge-air cooler), where that air is cooled before entering the engine's intake manifold. Cooling the charge air increases its density, which allows the engine to burn fuel more efficiently and produce consistent rated output — a critical requirement for a large diesel generator set like the DCA400SSI4F series. When the inter cooler pipe cracks, collapses, or loses a secure seal at its connections, boost pressure escapes before reaching the intake, causing the engine to run hotter, produce less power, and consume more fuel than normal.
