CSF F-Series High-Performance Heat Exchanger

CSF #8131/8131B

CSF upgraded the inlet/outlet design and improved the core specifications for better air-flow, water-flow, and improved cooling system performance. These updated features result in further lowering Intake Air Temperatures (IATs) of the air-to-water in-manifold charge cooler air cooler system for maximum performance.

The included hardware mounting kit is for applications that have a factory transmission oil cooler (OEM #17118625431).
