CSF 6009 Intercooler

CSF 6009 Intercooler for Ram Diesel Applications

The CSF 6009 intercooler is built for Dodge Ram 2500 and Ram 3500 diesel applications that need OE-style fitment with aluminum construction. Its 1 1/4-inch core thickness, 27 1/2-inch core length, and 24 5/8-inch core width support efficient charge-air cooling in a direct replacement format.

CSF’s New Style with 1 1/4" Core line focuses on drop-in fit and engineered performance for truck owners replacing a worn or damaged intercooler. This CSF 6009 unit uses an OEM-style tube-and-fin core design with aluminum core and tanks for a factory-style installation profile.

• Aluminum core and aluminum tank construction
• 1 1/4-inch core thickness
• 3-inch inlet and 3-inch outlet tubes
• Core dimensions: 27 1/2 inches long by 24 5/8 inches wide

Detailed Product Overview

Built for 2003-2009 Dodge Ram 2500 and Dodge Ram 3500 models, this intercooler is shaped to match OE-style mounting and airflow requirements. The aluminum core and tanks provide a durable replacement solution, while the tube-and-fin design follows the factory-style layout used in many heavy-duty diesel cooling systems. For buyers searching for a 2006 Dodge Ram 2500 intercooler replacement, a 2007-2009 Dodge Ram 3500 intercooler, or a CSF 6009 direct-fit intercooler for Ram diesel trucks, this unit aligns with those applications.

This part cross-references Chrysler 55057092AA and CH3012113 for the same application.

What It Helps Address

• Damaged or leaking intercooler cores
• Reduced charge-air cooling efficiency
• Fitment issues from non-OE-style replacement parts
• Cracked or corroded factory-style aluminum tanks
• Restoration of proper intercooler airflow path in Ram diesel trucks

Installation Notes and Tips

Verify the vehicle year and model before installation. This intercooler is listed for 2003-2004 Dodge Ram 2500 and Ram 3500, 2005 Dodge Ram 2500 and Ram 3500 with aluminum tank design, and 2006-2009 Dodge Ram 2500 and Ram 3500 with OE-style fitment notes. Confirm inlet and outlet tube size, mounting points, and surrounding cooling-system clearance before final assembly.

For best results, inspect charge-air hoses, clamps, and adjacent cooling components during replacement so the new intercooler can be installed into a clean, leak-free system.
