CSF Porsche 944 (NA and Turbo) High Performance Radiator

The unique B-Tube Technology in this CSF radiator is a real game-changer for keeping your 1983-1991 Porsche 944, including Turbo models, running cool. Unlike standard oval tubes, CSF's B-tubes are seam-brazed and shaped to increase the heat transfer surface area by about 15%. This means you get more efficient cooling, almost like having two smaller tubes working in tandem, which CSF calls 'dual liquid laminar flow'. It’s a smart design that allows for a thinner, lighter aluminum core without sacrificing strength or cooling power.

This isn't just about a better tube design; CSF also uses ultra-efficient, multi-louvered fins that are precisely aligned to maximize airflow. They even test these fin configurations in a wind tunnel to ensure maximum heat rejection for your specific application. The entire radiator is TIG-welded from all-aluminum construction, and the mounting brackets are CNC machined for a solid, durable fit. It's designed as a true drop-in replacement, meaning you won't need to modify anything on your 944 to install it, and you can even reuse your original hoses.

If you're pushing your 944 hard on the street or the track, or if you've got a high-horsepower build, this radiator is a solid choice. It’s built to handle the extra heat, and CSF backs it with a 2-year limited warranty. You can also opt for their shroud and dual SPAL fan kit to further enhance cooling performance.
