CSF 31mm High-Performance Aluminum Radiator for 08-15 Subaru Impreza WRX/STI 1-Row - Black

CSF has over five decades of expertise in manufacturing radiators, making them the trusted choice for keeping your engine cool and your Subaru WRX/STI performing at its peak. This high-performance radiator is designed for both street and track use, making it ideal for high horsepower builds as well as race vehicles that demand superior cooling performance in motorsports environments. Featuring a durable 2-Row core with CSF's exclusive B-Tube Technology, this radiator stands out with its innovative design. Unlike conventional oval “O” type tubes, CSF utilizes specially engineered "B-tubes" that are carefully formed and brazed over the seam for increased strength. This advanced construction allows for thinner, lighter aluminum material with enhanced cooling efficiency, giving you the performance of two smaller tubes within the same space. The B-Tube design also significantly increases the heat transfer surface area, offering a 15% improvement over regular tubes. Combined with ultra-efficient multi-louvered fins, carefully aligned to maximize airflow, this radiator ensures optimal heat rejection and superior cooling performance in demanding conditions.

Upgrade to the CSF High-Performance All-Aluminum Radiator for unmatched cooling efficiency, durability, and reliability in both everyday driving and high-performance racing environments. Experience the difference that decades of innovation and expertise bring to your vehicle’s performance.
