The Multiquip EE47721 is a genuine OEM Lower Tube, Air Filter, Cummins QSL9-G2, designed for the QSL9-G2 generator. As a factory-sourced component, it meets the exact dimensional and material specifications required for proper air filtration system function on this engine platform. If you're servicing or restoring the air intake assembly on a QSL9-G2 unit, this is the correct tube to install. DHS Equipment stocks this part to keep your Cummins-powered generator running at full capacity.
Key Features
- OEM Material and Dimensional Accuracy — Manufactured to Multiquip's original specifications, ensuring the tube maintains proper airflow geometry and sealing integrity within the air filter assembly.
- Direct-Fit for QSL9-G2 — Engineered specifically for the Cummins QSL9-G2 engine configuration, connecting to the existing air filter housing without modification to mounting points or ducting.
- Confirmed QSL9-G2 Fitment — Verified for use on QSL9-G2 series generators, eliminating guesswork when sourcing intake system components for this engine.
- Supports Clean Air Delivery — A correctly fitted lower tube maintains the sealed air path from the filter element to the engine intake, preventing unfiltered air from bypassing the system and causing accelerated wear.
- Critical Intake System Integrity — A cracked, loose, or incorrect lower tube can allow debris and contaminants into the engine, making this a genuine safety-relevant replacement when wear or damage is found during inspection.
The air filter lower tube forms part of the intake ducting that channels filtered air from the air filter housing into the engine. It creates a sealed passage that prevents dust, debris, and moisture from entering the engine ahead of or around the filter element. When this tube cracks, warps, or loses its sealing surface, unfiltered air can reach the engine, accelerating cylinder and valve wear and potentially causing serious internal damage over time. Replacing it with the correct OEM part restores the integrity of the entire air intake system.
