CSF Aluminum Radiator for 996 911 / 986 Boxster — 2-Row Core with B-Tube High-performance cooling engineered for street and track. CSF draws on 50+ years of radiator expertise to deliver reliable, race-ready temperature control for Porsche 996 911 and 986 Boxster models. This all-aluminum radiator features a compact 2-row core with CSF’s exclusive B-Tube Technology . B-shaped tubes are seam-brazed for strength, allowing thinner, lighter aluminum with superior heat transfer compared to conventional O-tubes. Increased heat transfer: B-Tubes boost tube surface area ~15% vs. standard designs for improved efficiency. Dual laminar flow: Internal geometry promotes two liquid streams within the same space for faster cooling. Precision multi-louvered fins: Optimized fin count and alignment maximize airflow and heat rejection; validated in CSF wind-tunnel testing. Durable construction: Brazed seams and all-aluminum build resist corrosion and endure track conditions. Ideal for high-horsepower builds, aggressive street use, and motorsports, this CSF radiator reduces operating temperatures and improves thermal stability under load. Upgrade your Porsche cooling system with proven performance and OEM-fit reliability.
