F8X M3 / M4 / M2 Comp Top Mount Charge-Air-Cooler - Crinkle Black Finish

When you hit boost on the S55 you feel every turbo spool, every gear change, and the engine pull hard. But heat kills consistency. Back to back laps on the track or repeated dyno pulls quickly show the limits of the stock top mount intercooler. The CSF Top Mount Charge Air Cooler keeps intake temps low and power steady. Longer sessions, harder pulls, and confidence in your BMW F80 M3, BMW F82 M4, or BMW F87 M2 mean you can drive flat out without worrying about heat soak.

CSF developed this cooler after extensive dyno and track testing. Tuned cars and aggressive driving conditions revealed that factory units could not keep up. The result is a dual pass, cross flow core 60 percent larger than stock, with carefully placed air dividers in both hot and cold end tanks. CFD analysis and real world testing ensured maximum heat transfer, reduced intake temps, and consistent performance under load. This is the cooler built for serious enthusiasts who push their S55s to the limit.
