C43 AMG Intercooler (M276 DE 30 AL)

The CTS Turbo High-Performance Intercooler is engineered to combat heat soak and maintain optimal charge air temperatures for the Mercedes-Benz 3.0L V6 biturbo M276 DE 30 AL engine. This upgrade significantly increases the external core volume by 134% over the stock intercooler, growing from 2.7L to 6.3L. Its core dimensions measure 222 mm x 297 mm x 95 mm, optimizing heat transfer and internal airflow. Constructed with CAD-optimized cast aluminum end tanks and validated through CFD simulations, this intercooler delivers exceptional cooling performance while maintaining a minimal pressure drop. This makes it an ideal component for both spirited street driving and demanding track use. It serves as a direct replacement for the factory Charge Air Cooler (Mercedes part number 276-090-02-14), requiring no modifications for installation. Key benefits include significantly lower Intake Air Temperatures (IATs), helping to keep charge air cool and dense for increased response and power, especially in tuned vehicles. The reduced pressure drop further enhances airflow. The kit includes 2.25-inch (57mm) aluminum charge pipes and all necessary hardware for a straightforward installation. It is designed as a direct fit replacement for the factory unit. This intercooler is compatible with a range of Mercedes-Benz models, including the C400 4MATIC (W205) from 2014-2023, C450AMG 4MATIC (W205) from 2015-2019, C43 AMG 4MATIC (W205) from 2016-2024, E43 AMG 4MATIC (W213) from 2016-2018, E450 AMG 4MATIC (W213) from 2018-2020, GLC 43 AMG 4MATIC (X253) from 2016-2023, and GLE 43 AMG 4MATIC (C292) from 2016-2022. An installation note indicates that the main circuit coolant hose may need to be disconnected on one side to re-install the radiator fan, though the fan will not make contact with the intercooler.
