CSF 7042O High-Performance All-Aluminum Radiator for Subaru WRX/STI

Description

The CSF 7042O high-performance all-aluminum radiator is engineered to optimize cooling efficiency for Subaru WRX and STI models from 2008 to 2015. With over five decades of manufacturing experience, CSF has developed a radiator that delivers exceptional heat dissipation and durability, making it suitable for both street driving and high-performance racing environments. The radiator features a 2-Row core with CSF’s exclusive B-Tube Technology, which replaces traditional oval tubes with precisely formed “B”-shaped tubes. This design increases the heat transfer surface area by approximately 15% and allows for dual liquid laminar flow, significantly improving cooling performance while maintaining a lightweight and robust structure. The ultra-efficient multi-louvered fins are meticulously aligned to maximize airflow, ensuring maximum heat rejection even under demanding conditions. Designed as a “Drop-in Fit,” this radiator installs directly into OEM locations without modifications, accepting all standard OEM components such as hoses, brackets, and fans. CNC-machined brackets and fittings provide a secure and durable connection, while the all-aluminum construction ensures excellent corrosion resistance and longevity. Additional features include a race-style drain plug for quick maintenance and a one-hour hand-polished mirror finish for an attractive appearance. Whether upgrading for increased horsepower or enhancing cooling for track days, the CSF 7042O radiator offers industry-leading technology and reliable performance to keep your Subaru running at its best.
