CSF High-Performance Left-Side Radiator for Porsche 996 and 997 Turbo (2002–2012)

Description

The CSF All-Aluminum Left Side Radiator is a high-performance coolant upgrade engineered to meet the rigorous demands of Porsche 996 / 997 Turbo and GT2 vehicles pushed hard on the street or track. Featuring CSF’s B-Tube core technology, this radiator offers superior heat rejection and cooling capacity compared to the restrictive OEM core. Precision TIG-welded aluminum construction and OEM-compatible inlet/outlet connections make this a true bolt-on replacement for the factory left-side radiator. When paired with the matching CSF Right Side Radiator, the system delivers balanced, race-ready cooling to help combat high engine temperatures and sustain power under extreme driving conditions. Durability and performance are engineered for both daily driving and high-boost, tuned applications.
