CSF Race-Spec 2-Row 42mm All-Aluminum Radiator for Select 2005-2021 Subaru (Black) - 7095B

Fits select 2005-2021 Subaru WRX, WRX STI, Impreza, Legacy, Outback, Forester, and Crosstrek models (Manual Transmission only). This high-performance radiator is a drop-in replacement engineered for both street builds and competitive motorsports.

The CSF 7095B (which supersedes CSF #7042) utilizes a 42mm 2-row core featuring exclusive B-Tube technology. Unlike standard "O" shape tubes, the B-Tube is formed from thinner, lighter aluminum and seam-brazed for superior strength. This design increases the heat transfer surface area by approximately 15% and encourages dual liquid laminar flow for maximum thermal rejection. The core is paired with ultra-efficient 6.5mm multi-louvered fins, precision-aligned to maximize airflow through the assembly.
