CSF's twin charge-air-cooler set keeps intake air temperatures down on the S63 twin-turbo V8. Designed with CFD analysis and 3D scanning, the custom liquid-to-air cores are the largest that fit the factory location and carry 100% more core volume per cooler than the OEM units. One-piece seamless air-inlet end tanks integrate the charge pipes for maximum strength, and integrated dual 1/8 NPT ports per cooler support E85 or methanol injection. A complete drop-in set with left and right coolers plus installation hardware. Crinkle Black finish with a lifetime warranty.
