CSF 7094B High-Performance 31mm 1-Row Aluminum Radiator - Black - Select Subaru 2005-2021

Fits select 2005-2021 Subaru Legacy, Outback, WRX, STI, Impreza, Crosstrek, and Forester models (Manual Transmission Only). This high-performance all-aluminum radiator is engineered for both daily street use and demanding track environments where cooling efficiency is critical.

The 7094B features CSF's exclusive B-Tube technology. Unlike traditional oval "O" type tubes, B-Tubes are formed from thinner, lighter aluminum and brazed over a seam, creating a stronger structure that increases heat transfer surface area by approximately 15%. This design promotes dual liquid laminar flow and is paired with ultra-efficient 6.5mm tall multi-louvered fins to maximize airflow and heat rejection.
