CSF Universal Drag Race / Tuck Radiator w/9in Spal Fan - 10.5in H x 10in L x 3.6in W - Black

The CSF KING Cooler is built for serious drag racing, specifically for import compacts. It addresses a common pain point for builders: getting a custom radiator can take weeks and cost a lot. CSF developed this universal unit to be readily available, fitting into multiple configurations thanks to its universal mounting brackets. The core design is where the real magic happens for keeping your engine cool under extreme conditions. It uses CSF's exclusive B-tube technology, which is a unique shape that increases the heat transfer surface area by about 15% compared to standard oval tubes. This design allows for dual liquid laminar flow, essentially giving you the cooling efficiency of two smaller tubes in the same space.

This radiator also features a triple-pass flow structure. That means your coolant travels across the core three times before exiting, which significantly lowers the outlet temperature. It’s a 2-row core design with multi-louvered fins, all carefully aligned and tested in a wind tunnel to maximize airflow and heat rejection. The whole package, including the radiator, the included 9-inch SPAL fan, and fittings, weighs in at a light 8.0 lbs, making it a great choice for weight-conscious builds. The black finish gives it a stealthy, high-end look.

This kit comes with threaded bungs that accept 1.25-inch slip-on fittings and standard -16 inlet/outlet connections, so you can easily adapt it to your plumbing. It also includes a drain plug bung with an M12 x 1.5p thread pitch. With a fluid capacity of 2.95 liters (0.78 gallons), it’s designed for efficient cooling in demanding drag racing scenarios.
