CSF Porsche 911 Turbo/GT3 RS/GT4 (991) Center Radiator

If you're pushing your 2013-2019 Porsche 911 hard, whether on the street or the track, keeping engine temperatures in check is critical. This all-aluminum radiator from CSF is built to handle the extra heat generated by high-horsepower builds and demanding motorsports use, offering a significant upgrade over the stock unit.

CSF has been making radiators for over 50 years, and this one uses their exclusive B-tube technology. Instead of a standard oval tube, these B-tubes are shaped and brazed for a stronger, lighter design that increases the heat transfer surface area by about 15%. This means more efficient cooling, like having two smaller tubes working in the same space as one large one. The radiator also features multi-louvered fins, precisely aligned to maximize airflow and heat rejection, all tested in a wind tunnel to ensure top performance.

You can expect a true drop-in fit with this radiator; no modifications are needed for installation. The OE-style brackets are CNC machined for durability, and the inlet and outlet connections are designed to match your factory hoses, so you can reuse your original or aftermarket ones. It's also designed to work with your factory AC condenser and fan shroud, making it a straightforward upgrade for serious cooling performance.
