Further Information
CSF brings over 5 decades of radiator manufacturing expertise to the B5 A4 1.8T platform. This high-performance all-aluminum radiator is engineered for both street and track use, delivering superior cooling in demanding conditions while maintaining factory integration.
The radiator features CSF's exclusive B-Tube Technology: specially engineered tubes brazed along the seam that are stronger than conventional O-tube designs while using thinner, lighter aluminum. The B-tube design with centered inlet creates dual liquid laminar flow and increases heat transfer surface area by approximately 15% compared to regular tubes, delivering the efficiency of two smaller tubes within the same space.
Ultra-efficient multi-louvered fins are precision-aligned and calculated for each application, then validated in CSF's wind-tunnel lab for maximum heat rejection.
Key Features:
- 2-Row, 42mm ultra-high-performance dual pass core with 45 B-tubes
- 6.5mm tall multi-louvered fins maximize surface area and airflow
- 100% all-aluminum TIG-welded construction with smooth satin finish
- CNC machined mounting brackets with OEM style inlet/outlet connections
- True plug-and-play installation requires no modifications
- Individually leak and pressure tested
Includes:
- Complete radiator assembly
- OEM style mounting brackets
- 2-year limited warranty
