CSF 02-07 Subaru WRX/STI All-Aluminum High-Performance Radiator with B-Tube Technology

Description

The CSF 02-07 Subaru WRX/STI Radiator is engineered for optimal cooling performance in both street and track environments. Constructed with a durable all-aluminum, dual-row 42mm core, this radiator features CSF’s exclusive B-Tube technology, which enhances heat transfer efficiency by approximately 15% over traditional tubes. The B-Tubes are carefully formed into a “B” shape and brazed over the seam, providing a stronger and lighter alternative to conventional oval-shaped tubes. This design allows for thinner aluminum usage while maintaining structural integrity, resulting in improved airflow and heat dissipation. The increased surface area from the middle-inlet seam brazing and the dual liquid laminar flow facilitate maximum cooling efficiency, making it suitable for high horsepower builds and motorsport applications. The radiator’s ultra-efficient multi-louvered fins, with a fin height of 6.5mm, are precisely aligned to maximize airflow and facilitate rapid heat rejection. Testing in CSF’s wind-tunnel lab ensures that each unit meets industry-leading standards for heat dissipation. Designed as a direct drop-in replacement, this radiator installs in the OEM location without modifications, accepting all factory components including quick-connect hoses, condenser, mounting brackets, and fan shroud. CNC-machined brackets and fittings guarantee a perfect fit and durability, complemented by a sleek black finish that provides a high-end stealth appearance. An all-aluminum race-style drain plug completes the design, ensuring reliable operation under demanding conditions. Whether upgrading for increased performance or replacing an aging radiator, the CSF WRX/STI radiator offers an efficient, reliable solution that enhances engine cooling and overall vehicle performance.
