Are you looking to enhance the cooling performance of your Audi B8 S4 or S5? Look no further than the CSF High-Performance All-Aluminum Radiator. With over 5 decades of experience in radiator manufacturing, CSF has developed a product that is a must-have for both street and track use. This radiator is designed to keep your engine running at its best, providing the cooling efficiency needed for high horsepower builds and race vehicles.
  • CSF's Exclusive B-Tube Technology: Unlike traditional oval-shaped tubes, CSF's innovative "B-tubes" are designed to maximize heat transfer surface area, increasing efficiency by approximately 15%.
  • Lightweight and Durable: The use of thinner, lighter aluminum material not only enhances cooling efficiency but also makes the radiator stronger than conventional designs.

Superior Design and Efficiency

The CSF High-Performance Radiator is not just about raw power; it's about precision engineering. The 2-Row core design, combined with CSF's exclusive B-Tube Technology, ensures that your engine stays cool under the most demanding conditions. The multi-louvered fins are meticulously aligned to maximize airflow through each radiator core, ensuring optimal heat rejection efficiency.
  • Optimized Heat Transfer: The innovative design of the "B-tubes" and the increased surface area of the fins result in superior heat transfer, keeping your engine at a stable temperature.
  • Engineered for Performance: Whether you're driving on the street or at the track, this radiator is designed to handle high-performance applications, providing the cooling power you need.

Perfect Fit for Your Audi B8 S4 & S5

CSF's High-Performance Radiator is a perfect fit for a wide range of Audi B8 S4 and S5 models, including the A4 Quattro, A5 Quattro, A6 Quattro, A7 Quattro, Q5, S4, S5, and SQ5. This radiator is engineered to meet the specific cooling needs of these vehicles, ensuring that your Audi performs at its peak.
  • Wide Range of Applications: This radiator is designed to fit various Audi B8 S4 and S5 models, making it a versatile choice for any Audi enthusiast.
  • Professional Installation: While this radiator is easy to install, for the best results, we recommend having a professional perform the installation to ensure optimal performance and longevity.
