The W205 C63 is already a potent animal, boasting 469hp/479tq from its 4.0 bi-turbo V8. After adding a bit of ECU tuning to the mix, we found air intake temperatures quickly become an issue. CSF have come to the rescue with their new heat exchanger kit!

This new heat exchanger is a direct OEM replacement and features a 2-row, 42mm core with CSF’s exclusive B-tube technology.

In their recent testing, CSF found their heat exchanger reducing charge air temperatures by as much as 68% and reducing heat soak by as much as 400% compared to stock! The massive reduction in heat soaking means you can run your C63 faster and harder than ever before without heat issues!


  • Lower charge air temperatures
  • Direct fit – no modifications required for installation
  • 2-row, 42mm core
  • CSF’s exclusive B-tube technology
  • Mirror finish hand-polish
