The CSF heat exchanger is designed to perform on the street and track, and is essential for cars that need additional cooling power.
Triple-Pass Flow Structure allows coolant to flow across the radiator cores three times before exiting, keeping the outlet temperature as low as possible.
This radiator features a 2-row core with CSF's unique B-Tube technology: Unlike the standard oval "O" type radiator tube, CSF uses a specially designed "B" shaped tube. These "B" tubes are carefully shaped and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling performance) because this design is stronger than the standard welded "O" shaped tubes.
To achieve maximum heat removal efficiency, the cooler has been tested in a wind tunnel laboratory.
