CSF Porsche 991.1/981 Left Performance Radiator

CSF #7066 Left All-Aluminum Performance Radiator is a high-performance cooling upgrade designed for selected Porsche 991.1 Carrera and 981 Boxster/Cayman applications. Positioned on the left side of the front cooling system, it is engineered to improve thermal management during demanding street and track driving.

The radiator features a 2-Row 42mm Core with CSF B-Tube Technology, designed to increase heat-transfer surface area while maintaining efficient coolant flow. CSF rates this core design at approximately 20% greater efficiency than conventional radiator designs.

A 6.5mm multi-louvered fin design increases the available surface area and promotes efficient airflow through the core, helping the radiator dissipate heat effectively under sustained thermal load.

The radiator is constructed from all-aluminum components with 100% TIG-welded end tanks, complemented by CNC-machined brackets and fittings. This construction provides durability and precise fitment for performance-oriented applications.

OEM-style machined inlet and outlet connections are designed around the factory cooling-system connections. The radiator also accommodates the OEM A/C condenser and fan shroud, helping maintain the original cooling-system configuration.

CSF #7066 is engineered as a Plug-and-Play Drop-In Fit, requiring no modifications for installation. Each radiator is individually leak and pressure tested before leaving the factory.

Applications include selected Porsche 991.1 Carrera, Carrera S, Carrera 4, Carrera 4S, Carrera GTS and Targa models, as well as 981 Boxster and Cayman variants including the Boxster Spyder and Cayman GT4.

As the left-side counterpart to CSF #7067, the #7066 is designed for Porsche owners seeking an all-aluminum radiator upgrade while retaining the factory cooling-system layout and installation points.
