The Multiquip EE53916 is a genuine OEM CAC to Engine Tube designed for QSM11/Mara 225kW generator systems. As a factory-sourced component, EE53916 delivers an exact match to the original part in material grade, diameter, and routing geometry — no guesswork on fitment for QSM11 series units. Sourcing OEM means you get the same specification that left the factory, keeping the charge air cooling circuit operating as engineered. If you're servicing a QSM11-powered Multiquip unit, this is the correct tube for the job.
Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional specification of the original charge air cooling circuit tube, ensuring correct pressure handling and thermal compatibility for the QSM11/Mara 225kW application.
- Direct CAC Circuit Replacement — Routes directly between the charge air cooler outlet and the engine intake, matching original connection points and hose coupler interfaces for a straightforward installation.
- QSM11 Series Fitment — Confirmed fitment for QSM11/Mara 225kW Multiquip generator systems; verify your model code before ordering to ensure accuracy.
- Charge Air Integrity — A correctly seated CAC tube maintains the pressurized airflow from the cooler to the engine intake; a cracked or leaking tube causes boost loss, power reduction, and elevated exhaust temperatures that can accelerate engine wear.
- Fuel System Compliance — Maintaining an intact charge air path on a diesel generator is critical to proper fuel metering and combustion efficiency; a compromised tube can result in out-of-spec emissions and irregular engine behavior under load.
The CAC to Engine Tube carries cooled, compressed intake air from the charge air cooler to the engine's intake manifold. On turbocharged diesel generators like the QSM11/Mara 225kW, the turbocharger compresses intake air — which heats it significantly — and the charge air cooler drops that temperature before it reaches the engine. This tube is the final link in that circuit. A crack, loose connection, or collapsed tube bleeds off boost pressure, starving the engine of the dense, cool air it needs to produce rated power and maintain clean combustion. Over time, a failing tube will cause hard starting, black smoke, and reduced generator output.
