Further Information
CSF brings over 5 decades of radiator manufacturing expertise to the Audi B8 S4/S5 platform. This high-performance all-aluminum radiator is engineered to deliver superior cooling on both street and track, making it essential for high-horsepower builds and motorsports applications where thermal management is critical.
Featuring CSF's proprietary B-Tube Technology, the radiator core achieves approximately 15% greater heat transfer surface area compared to conventional O-shaped tubes while using thinner, lighter aluminum material. The specially brazed B-tubes create dual liquid laminar flow patterns and deliver the cooling efficiency of two smaller tubes within the same physical footprint, resulting in stronger construction with superior thermal performance.
Key Features:
- 2-Row 42mm dual core with CSF's exclusive B-Tube Technology
- Ultra-efficient multi-louvered fins with 6.5mm fin height for maximum airflow
