CSF

CSF builds radiators, intercoolers, oil coolers and transmission coolers for BMW, Porsche, Nissan GT-R, Toyota GR Supra and other performance cars. This collection covers CSF high-performance main and auxiliary radiators, charge air coolers, race-spec oil coolers and the fittings to install them.

Heat is what limits a tuned or tracked car, and CSF coolers are made to hold temperatures down through repeated hard use. Auxiliary radiators for the F87 M2 and F8X and G8X M3 and M4 are a common first upgrade. The G90 M5 charge air cooler and race-spec oil coolers for the E60 M5 and S54 swaps cover more specialized builds, and classic BMWs like the E28 M5 and E24 M6 are covered too.

We curate the CSF coolers enthusiasts ask for most, and every one is genuine, sourced through authorized distributors. Each listing is made for a specific engine and chassis, and some coolers need fittings or lines listed separately. CSF parts are final sale unless defective, so check the listing notes before you order.
