Further Information
CSF brings over 5 decades of radiator manufacturing expertise to this high-performance cooling solution engineered for 08-14 Subaru WRX/STI and 15-21 WRX platforms. Built for street and track applications, this 1-row 31mm radiator delivers the added cooling capacity demanded by high-horsepower builds and motorsports environments.
The radiator features CSF's proprietary B-Tube Technology, which uses specially engineered tubes with a seam-brazed design that are stronger than conventional O-tube welded construction while utilizing thinner, lighter aluminum materials. This innovation increases heat transfer surface area by approximately 15% compared to regular tubes, effectively delivering dual liquid laminar flow within the same space footprint.
Key Features:
- CSF's exclusive B-Tube Technology with seam-brazed construction for superior strength and efficiency
- Ultra-efficient 6.5mm tall multi-louvered fins precisely aligned for maximum airflow and heat rejection
