CSF's High-Performance All-Aluminum Radiator for 99-06 VW Golf, GTI, Jetta, and GLI combines decades of cooling expertise with advanced engineering for street and track applications. Designed to handle high horsepower builds and motorsports environments, this radiator delivers superior thermal performance without compromise.
The 2-Row 42mm core features CSF's proprietary B-Tube Technology, which uses specially engineered tube geometry that increases heat transfer surface area by approximately 15% compared to conventional O-shaped tubes. These B-tubes are brazed over the seam for superior strength while allowing the use of thinner, lighter aluminum materials. Multi-louvered fins with 6.5mm fin height are precisely aligned and wind-tunnel tested to maximize airflow and heat rejection efficiency.
