CSF 7065 KING Cooler Universal Drag Race / Tuck Radiator with 9-inch SPAL Fan

The CSF 7065, famously known as the "KING Cooler," is a high-performance universal radiator engineered specifically for sport compact drag racing and tight "tuck" engine bay configurations. Developed through extensive R&D with leading North American drag builders, this cooling system replaces the need for expensive, long-lead-time custom units with a professional-grade, off-the-shelf solution.

This radiator utilizes a triple-pass flow structure, forcing coolant across the core three times to achieve significantly lower outlet temperatures. The 3.5-inch thick, 2-row core features CSF’s exclusive B-Tube technology. Unlike standard "O" shaped tubes, B-Tubes are seam-brazed to increase heat transfer surface area by approximately 15% while providing superior structural rigidity, allowing for thinner and lighter aluminum construction without sacrificing strength.

• Triple-Pass Efficiency: Maximizes coolant dwell time for superior heat rejection in high-stress applications.
• B-Tube Technology: Engineered tube shape provides the surface area of two smaller tubes within the same space.
• SPAL Cooling: Includes a high-performance 9-inch SPAL fan for consistent airflow in low-speed or stationary conditions.
• Versatile Plumbing: Supplied with threaded bungs and a kit to accept 1.25-inch slip-on or -16 AN inlet/outlet connections.
• Show-Grade Finish: Features a 1-hour hand-polished mirror finish.
