All-Aluminum Auxiliary Radiator

The CSF #7060 is a high-performance, all-aluminum auxiliary radiator engineered for Porsche 991 911, 981, and 982 Cayman/Boxster models. With over 5 decades of manufacturing experience, CSF delivers a radiator designed for both street performance and track use. This unit is crucial for high horsepower builds and motorsports environments requiring enhanced cooling. This radiator utilizes a 2-row, 42mm core featuring CSF's exclusive B-Tube Technology. Unlike standard oval tubes, CSF's "B-tubes" are seam-brazed, increasing the heat transfer surface area by approximately 15% and providing dual liquid laminar flow for superior efficiency. The core is further enhanced with ultra-efficient, multi-louvered fins precisely aligned to maximize airflow and heat rejection, validated in wind-tunnel testing. The CSF #7060 is designed as a true plug-and-play "drop-in" fit, eliminating the need for modifications. It features OE-style, CNC-machined brackets and fittings for durability and precise fitment, ensuring compatibility with OEM hoses. The radiator accepts the OEM AC condenser and fan shroud, simplifying installation. It is individually leak and pressure tested for reliability. Fitment includes a wide range of Porsche 911 (991.1, 991.2), 718 Boxster (982), and 718 Cayman (982) models from various years and trims, including Carrera, GTS, S, and T variants. However, a critical fitment note advises verifying compatibility with VIN for some GTS 4.0 models, as either CSF #7060 or CSF #7068 may be the correct OE replacement.
