CSF Top Mount Charge-Air-Cooler – 2014+ BMW M3 / M4 (F8X) | S55 | Gloss Black

Eliminate heat soak and unlock more consistent power from your F8X BMW M3 or M4's S55 twin-turbo inline-6 with the CSF Top Mount Charge-Air-Cooler. The factory S55 charge-air-cooler is a well-documented heat soak point — its limited core volume allows intake charge temperatures to climb rapidly under sustained boost, reducing power output and increasing knock risk. CSF's top mount CAC replaces the factory unit with a significantly larger, more efficient charge-air-cooler core in a direct-fit package, delivering dramatically lower and more consistent charge air temperatures for improved power output and reliability across track sessions and spirited street driving. Finished in a durable gloss black coating for a premium underhood appearance.

Key Features

• Significantly Increased Core Volume: Larger charge-air-cooler core than the factory S55 unit — dramatically improved cooling capacity for lower, more consistent charge air temperatures under sustained boost
• Reduced Heat Soak: Addresses the factory S55 CAC's well-documented heat soak limitation — more consistent power output across repeated pulls, track sessions, and sustained high-load driving
• Direct Fit: Engineered as a direct replacement for the factory 2014+ BMW F80 M3 / F82 M4 top mount charge-air-cooler — uses OEM mounting points and connections for a clean installation
• Gloss Black Finish: Durable gloss black coating for a premium, show-quality underhood appearance
• CSF Quality: Manufactured by CSF — a globally recognized leader in high-performance cooling solutions trusted by enthusiasts and professional motorsport teams worldwide
