Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specifications for the QSM11 charge air cooling circuit, ensuring correct pressure rating and hose durability under sustained boost conditions.
- Exact-Fit Routing — Matches the original lower CAC line geometry so it seats correctly at both connection points without cutting, reshaping, or adapting the line.
- QSM11 Fitment — Confirmed for Multiquip QSM11-powered equipment; verify your model against part number EE48715 before ordering.
- Charge Air Integrity — A properly functioning lower CAC line maintains full boost pressure delivery to the engine, supporting rated power output and fuel efficiency across heavy-duty applications.
- Boost System Safety — A cracked or deteriorated charge air line can cause boost leaks, overheating, and engine derating; replacing with a genuine OEM line restores safe, controlled combustion air delivery.
The lower charge air cooler (CAC) line carries compressed, cooled air from the charge air cooler to the engine intake manifold. By reducing the temperature of air entering the engine after turbocharging, the CAC system allows the Cummins QSM11 to run a denser air charge, which supports proper combustion, rated horsepower, and emissions compliance. When the lower CAC line cracks, collapses, or develops a leak, boost pressure drops, the engine loses power, runs hotter than normal, and may trigger fault codes or derate — making prompt replacement critical to keeping the machine operating within spec.
