With over 5 decades of experience manufacturing radiators, CSF is a trusted name.
A CSF High-Performance All-Aluminum Radiator is essential for keeping your engine cool and your 996 911/986 Boxster running optimally.
Designed for performance on the street or track, this radiator is necessary for high horsepower builds and vehicles needing enhanced cooling in motorsports.
Featuring a 2-Row core with CSF's exclusive B-Tube Technology, CSF utilizes a specially engineered tube shaped like a 'B' instead of a regular oval 'O' type radiator tube.
These 'B-tubes' are formed and brazed over the seam for sealing.
This design allows CSF to use thinner and lighter aluminum material, which offers better cooling efficiency due to its strength compared to standard 'O' shape tubes that are welded.
The design increases the heat transfer surface area of the tubes by about 15% over regular tubes, achieving the efficiency of two smaller tubes versus one large tube within the same space.
With 'B-tubes', dual liquid laminar flow is possible.
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.
