CSF Radiators are all aluminum rRacing Radiators that are TIG welded from the highest quality military grade aluminum available. They aerodynamically engineered using OE radial specifications, and are a drop in fit requiring no modifications. Designed with industry first “B-Tube” technology, these new units will keep the most sophisticated and demanding engines cool in the most extreme temperatures and driving conditions. Using their state-of-the-art ISO 9002 engineering and testing facilities, these radiators have undergone industry leading; leak, thermal cycle, burst pressure, vibration, and wind tunnel testing. Each individual radiator is meticulously handcrafted by a master class welder before being perfected with their proprietary 30-minute Sho-Stopper mirror finish” polishing technique. These radiators are ideal for drag, drift, circuit, off-road, track, rally, and daily use.
