The Multiquip EE54131 Upper CAC Line Cummins QSM11 Long is a genuine OEM charge air cooler line designed for QSM11-powered equipment. As an authorized Multiquip OEM part, EE54131 is manufactured to the same specifications as the original component, ensuring a direct, hassle-free installation on QSM11 applications. Sourced directly through DHS Equipment, this part delivers the exact routing, connection dimensions, and material grade required for proper charge air cooling system operation. If you are servicing or rebuilding the charge air cooler circuit on a QSM11-equipped machine, this is the correct upper line for the job.
Key Features
- OEM-Grade Charge Air Line Construction — Built to withstand the pressure cycling and heat exposure demands of a turbocharged charge air cooler circuit, using materials that match the original Multiquip specification.
- Direct-Fit Upper CAC Routing — Engineered to follow the exact upper-side routing of the QSM11 charge air cooler circuit, connecting to OEM ports without cutting, splicing, or adapter fittings.
- QSM11 Application Confirmed — Verified fitment for QSM11-powered Multiquip equipment; use model code QSM11 to confirm compatibility before ordering.
- Sustains Charge Air Efficiency — A correctly functioning upper CAC line maintains full charge air pressure delivery to the engine, supporting proper combustion, power output, and fuel efficiency. A cracked or leaking line causes boost loss and reduced performance.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip replacement, carrying the same part number EE54131 as the original component for straightforward parts verification.
The upper charge air cooler (CAC) line carries compressed, heated air from the turbocharger outlet to the charge air cooler, where it is cooled before entering the engine intake. On Cummins QSM11 engines, maintaining a sealed and intact CAC line is critical — any leak or collapse in the line reduces boost pressure, which directly impacts engine power, efficiency, and emissions compliance. A worn or damaged upper CAC line can cause sluggish performance, overheating, and excessive fuel consumption, making timely replacement essential to keeping the engine operating at its rated output.
