CSF Radiator 42mm 2-Row Aluminum Core with B-Tube Technology

CSF Radiator 42mm 2-Row Aluminum Core with B-Tube Technology Upgrade cooling performance with the CSF 42mm 2-row aluminum core radiator. Engineered to outperform factory units, this radiator combines increased core thickness, an additional cooling row, and higher fluid capacity to deliver superior heat absorption and dissipation for demanding driving conditions. Thicker 42mm 2-row core – More coolant volume and surface area for stable operating temperatures. B-Tube Technology – Exclusive B-Tube design boosts heat transfer by approximately 15% versus standard oval-welded tubes. Multi-louvered fins – High-efficiency fin geometry maximizes airflow through the core for faster cooling response. Aluminum construction – Lightweight, corrosion-resistant materials for long-lasting performance and improved vehicle weight balance. Direct-fit replacement – Designed to integrate with factory mounting points for easy installation (vehicle-specific fitment required). Ideal for performance, towing, or high-temperature environments, the CSF 42mm radiator helps reduce overheating, lower operating temperatures, and protect engine components. Trust CSF’s advanced engineering to keep your engine cooler under load.
