The Multiquip EE45444 is a genuine OEM CAC to Turbo Tubing SS Cummins QSL9-G2, designed for Multiquip generator equipment powered by the Cummins QSL9-G2 engine. As a direct OEM replacement sourced through Multiquip, EE45444 meets the original engineering specifications for this charge air circuit connection. This part is confirmed for use on QSL9-G2 series generators and ships as a direct replacement for the factory-installed component. Whether you are completing a scheduled service or addressing a failure, the EE45444 gets your machine back to full operation without guesswork.
Key Features
- Stainless Steel Charge Air Construction — Built from stainless steel (SS) for resistance to the elevated temperatures and pressures present in the charge air circuit between the CAC and turbocharger.
- Exact OEM Geometry — Matches the original routing, diameter, and end connections so the tubing seats correctly against both the charge air cooler outlet and turbocharger inlet without rework.
- Confirmed Fitment for QSL9-G2 — Verified for Multiquip generator models powered by the Cummins QSL9-G2 engine, giving you confidence before the part ever ships.
- Maintains Charge Air Efficiency — A properly sealed CAC-to-turbo connection preserves boost pressure and intercooler performance; a cracked or leaking tube causes power loss, elevated exhaust temperatures, and hard starting.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip component, ensuring material grade and dimensional accuracy consistent with the original specification for this engine platform.
The CAC-to-turbo tubing is the rigid or semi-rigid conduit that carries compressed, heat-saturated air from the turbocharger outlet into the charge air cooler (CAC), or in the return direction, delivers cooled charge air back toward the intake. On a Cummins QSL9-G2-powered generator, this tube operates under positive boost pressure and significant heat cycling, making material integrity and a leak-free seal critical to engine output and fuel efficiency. When this tubing cracks, collapses, or loses its end seals, boost pressure escapes before it reaches the combustion chamber, resulting in reduced power output, increased fuel consumption, and potential over-temperature conditions that can accelerate wear on other engine components.
