New from CSF – the King Cooler drag racing radiator. This radiator is efficient, compact, and lightweight, and is suitable for engines generating up to 1,500 horsepower in racing conditions. See more details below.

Official Release:

The King Cooler by CSF is designed to be the most efficient, compact, and lightweight drag-race radiator ever developed. With a universal design and included mounting brackets, this new radiator can be mounted in multiple configurations and vehicle set-ups. This radiator is most popular with sport compact drag racing vehicles, but can be used in any drag-race environment. Suitable for engine up to 1500 hp in drag-race conditions.

The radiator uses a 3.5″ 2-row core with CSF’s exclusive B-Tube technology. This is the world’s largest 2-row core, allowing for maximum flow, weight reduction and airflow balance in the cooling system of a drag-race vehicle. CSF’s 2-row “B-Tube” core is the equivalent of a 4 row conventional core. A B-Tube core is 15% more efficient than a conventional core of equal thickness. The radiator also comes complete with an integral fan shroud that uses a low profile high flow SPAL electric fan (included).
