CSF is an Industry leader in Performance and OE replacement radiator units, with a wide selection of everything you need to keep your car cool. Each piece manufactured and assembled in house, for a sharp, "Show Stopper" finished product that will preform just as good as it looks.

In an effort to expand CSF’s Subaru product lineup, we have redesigned two of our existing best sellers to include an expanded year range. As of November 2021, new versions of our WRX and STI radiators will include a “Multi-Combo Fit” Fitting.

Supersedes CSF #7042 – Note: If you have a 7042 and wish to use it on a 2015-2021 WRX the Turbo Return Pipe on Top Right-Hand Side End Tank must be capped off.
