CSF High-Performance All-Aluminum Radiator for 2002-2007 Subaru WRX/STI
For over 50 years, CSF has been at the forefront of radiator manufacturing, and their expertise shines through in the CSF High-Performance All-Aluminum Radiator. If you own a 2002-2007 Subaru WRX or STI, this radiator is designed to keep your engine cool, whether you’re hitting the streets or pushing the limits on the track. It’s an essential upgrade for anyone looking to enhance performance, especially for high horsepower builds or race vehicles that demand superior cooling capabilities.
Innovative B-Tube Technology
What sets this radiator apart is CSF's exclusive B-Tube Technology. Unlike standard oval "O" type tubes, the specially engineered "B-tubes" are designed to maximize heat transfer efficiency. This design not only allows for a thinner and lighter aluminum construction but also increases the heat transfer surface area by approximately 15% compared to conventional tubes. This means that within the same space, you get the efficiency of two smaller tubes rather than one large tube, resulting in improved cooling performance and "dual liquid laminar flow."
Performance-Driven Design
The radiator features a 2-row, 42mm core with ultra-efficient multi-louvered fins, meticulously aligned to optimize airflow through the radiator. Each fin is engineered for maximum surface area contact, ensuring that your WRX/STI stays cool under pressure. The CSF radiator is a true drop-in fit, meaning you won't need to make any modifications during installation. It comes with CNC machined brackets and fittings for unmatched durability, and the inlet and outlet connections are designed to match OE specifications, allowing you to reuse your OEM hoses or aftermarket options.
