CSF 7066 High-Performance Left Side Radiator for Select Porsche 2012-2016 (911 / Boxster / Cayman)

Fits select 2012-2016 Porsche 911, Boxster, and Cayman models (991.1 / 981).

The CSF 7066 High-Performance All-Aluminum Radiator is engineered for Porsche owners who demand superior thermal management on both the street and the track. This left-side radiator serves as a direct drop-in replacement for the factory unit, offering a significant upgrade in cooling capacity and durability. Built with a 42mm 2-row core, it utilizes CSF’s exclusive B-Tube technology, which increases heat transfer surface area by approximately 15% compared to standard oval tubes. This design provides the efficiency of two smaller tubes in the space of one while maintaining a lightweight, high-strength structure.

Each unit features a 6.5mm multi-louvered fin height for maximum airflow efficiency and heat rejection. To ensure a lifetime of performance under high-pressure conditions, the end tanks are 100% TIG-welded to the core, and all mounting brackets and inlet/outlet connections are CNC-machined for an exact factory fit. The radiator accepts the OEM AC condenser and fan shroud with no modifications required for installation.
