CSF 7095 High-Performance 2-Row 42mm Aluminum Radiator for Select Subaru 2005-2021

Fits select 2005-2021 Subaru Impreza, WRX, STI, Legacy, Outback, Crosstrek, and Forester models equipped with manual transmissions.

The CSF 7095 High-Performance Aluminum Radiator is engineered for demanding street and track applications where thermal management is critical. Featuring a massive 42mm 2-row core, this radiator utilizes CSF's exclusive B-Tube technology. Unlike standard "O" shape tubes, the B-tube design is seam-brazed and reinforced, allowing for thinner, lighter aluminum while increasing the heat transfer surface area by approximately 15%. This creates the cooling efficiency of two smaller tubes within a single large-tube footprint for superior liquid laminar flow.

Built for durability and ease of installation, this unit features 100% TIG-welded construction and CNC-machined mounting brackets to ensure a true drop-in fit without modifications. To maximize airflow, CSF employs ultra-efficient 6.5mm tall multi-louvered fins, which are wind-tunnel tested for maximum heat rejection efficiency.
