CSF Front-Mount Heat Exchanger — S58 (G80 M3 / G82 M4 / G87 M2)

$1,105.00

CSF front-mount heat exchanger for the S58 — the heat-rejection side of the charge-air cooling system in the G8x M3/M4 and G87 M2. The S58 cools its intake charge through a coolant loop; this front radiator is what removes that heat. The factory exchanger is a single-row, 35mm core with plastic tanks — fine stock, the limiter once the car is making more and seeing repeat pulls or track time.

What CSF changes

A 2-row, 42mm all-aluminum core with B-Tube geometry and TIG-welded aluminum tanks in place of the OEM plastic/crimp construction. Ships with upper and lower rock guards and a transmission-cooler mounting kit, and drops into the factory location. CSF developed it over 100+ track hours.

Finishes

We spec these with a Thermal Heat Dispersion coating by default — an emissivity coating that helps the core radiate heat away, which is exactly what you want on a cooler. Prefer to skip it? Raw or Black are available for less. Choose above.

Fitment

S58 — G80/G81 M3 (incl. Competition, CS), G82/G83 M4 (incl. Competition, CSL), and G87 M2 / M2 CS. Confirm your chassis in the selector.

This is the heat-exchanger-side core of an S58 Stage 2 build. The Stage 2 Kit — S58 packages the matched parts + calibration for 8% under à la carte.

WHY WE SHIP CSF
CSF builds the radiators, heat exchangers, and charge coolers we use when the factory cooling stack can no longer keep up with the load a tuned car puts on it. The cores are engineered to factory fitment, so the upgrade goes in at the OEM locations without fabrication. On the heat-exchanger-cooled engines, the charge cooler is often the single highest-leverage cooling part, and CSF's units carry the thermal capacity to keep intake temps stable through repeated pulls. We ship CSF where a build needs more cooling than stock without giving up clean, factory-style integration.
