The Aeroflow Performance race series intercooler cores are designed for fabricators who wish to custom make their own intercooler. This makes it great for custom applications where conventional size and shape intercoolers do not work. This race series core provides the best cooling capacity, while safely increasing horsepower to provide street and race proven performance no matter the application. The tube and fin core is a straight through low restriction design for less pressure drop, resulting in higher flow and reduced lag time. They are available in universal cores sizes and raw alloy to allow anything to be welded to it.
