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

CSF has over 50 years of expertise in radiator manufacturing, making their High-Performance All-Aluminum Radiator the ideal choice for keeping your engine cool and your Subaru WRX/STI performing at its peak. Designed for both street and track use, this performance radiator is engineered to handle high horsepower builds and race vehicles that require superior cooling performance in demanding motorsports environments. Featuring a 2-Row core, this radiator incorporates CSF's exclusive B-Tube Technology—an advanced design that enhances cooling efficiency.

This innovative design allows for thinner, lighter aluminum material while increasing the heat transfer surface area by approximately 15% compared to traditional tubes, resulting in improved heat dissipation. Additionally, ultra-efficient multi-louvered fins are precisely aligned to optimize airflow, delivering superior heat rejection performance in any driving condition.

Choose the CSF High-Performance All-Aluminum Radiator for unmatched durability, cooling efficiency, and performance in both everyday driving and intense motorsport conditions. Its advanced B-Tube Technology and precision-engineered components ensure that your vehicle stays cool under pressure, making it the go-to solution for serious Subaru WRX/STI enthusiasts looking to maximize engine performance and reliability.
