With over 5 decades of experience manufacturing radiators, CSF is a leader in the industry.
A CSF High-Performance All-Aluminum Radiator is essential for keeping your engine cool and your 996/997 running optimally.
Designed for performance on the street or at the track, a performance radiator is necessary for high horsepower builds and vehicles needing enhanced cooling in motorsports.
This radiator features a 2-Row core with CSF's exclusive B-Tube Technology.
Unlike a regular oval shape 'O' type radiator tube, CSF employs a specially engineered tube shaped like a 'B'.
These 'B-tubes' are formed and brazed over the seam to create a seal.
CSF can utilize thinner and lighter aluminum material due to this design, which is stronger than standard 'O' shape tubes that are welded.
The design, with the inlet in the middle of the seam-brazed tube, increases the heat transfer surface area of the tubes by about 15% compared to regular tubes, producing the efficiency of two smaller tubes versus one large tube within the same space.
With 'B-tubes', you achieve 'dual liquid laminar flow'.
CSF also incorporates ultra-efficient multi-louvered fins that are precisely aligned to maximize air movement through each radiator core.
Fin specifications are measured and calculated for each application and tested for maximum heat rejection efficiency in a wind-tunnel lab.
