CSF 05-11 Porsche 911 Carrera/GT3 RS (997) Left Side Radiator

This is the left-side radiator for your 2005-2012 Porsche 911 Carrera or GT3 RS (997 chassis). It's a direct replacement for the original, designed to keep your engine running cool whether you're on the street or the track. CSF has been making radiators for over 50 years, so they know how to build them right.

What sets this radiator apart is its all-aluminum construction and CSF's B-tube technology. Instead of standard oval tubes, these use a specially shaped 'B' tube that increases the heat transfer surface area by about 15%. This means it can dissipate heat more efficiently, giving you better cooling performance, especially in high-horsepower builds or demanding driving conditions. The radiator also features louvered fins that are precisely aligned to maximize airflow through the core, further improving its cooling ability. It's built with CNC-machined brackets and fittings for a solid connection, and the inlet and outlet are designed to match the factory locations, so you can reuse your original hoses.

This radiator is a true drop-in fit, meaning no modifications are needed for installation. It's also designed to work with your original AC condenser and fan shroud, making the swap straightforward. It comes with a smooth satin finish and is individually leak and pressure tested before it leaves the factory.
