Description

CTS Turbo Performance Intercooler – Mercedes 43 AMG (M276 DE 30 AL)

CTS Turbo has developed a high-performance intercooler upgrade designed specifically for the 3.0L V6 biturbo (M276 DE 30 AL) engine. This intercooler significantly improves cooling efficiency, helping to maintain optimal intake air temperatures for better power delivery and reliability.

Featuring a larger and more efficient core, measuring 297 mm x 222 mm x 95 mm, this intercooler increases external core volume by 134% compared to the factory unit. Engineered using CAD-optimized cast aluminum end tanks and advanced CFD simulations, it ensures improved airflow and heat dissipation with minimal pressure drop. Whether on spirited drives or occasional track use, this upgrade helps the engine perform at its best under demanding conditions.

Built with a durable anti-corrosion coating, the CTS Turbo intercooler is designed for long-lasting performance and reliability. It installs as a direct replacement, requiring no modifications, making it an easy upgrade for improved cooling and throttle response.

Factory vs. CTS Turbo Core Comparison:

• Stock intercooler: 207 mm x 200 mm x 65 mm = 2.7L volume
• CTS Turbo intercooler: 297 mm x 222 mm x 95 mm = 6.3L volume

Key Features:

• Significantly lower intake air temperatures (IAT), keeping charge air cool and dense.
• Improved throttle response and power output, ideal for tuned vehicles.
• Optimized airflow with reduced pressure drop for better efficiency.
• Upgraded 2.25″ (57mm) aluminum charge pipes for improved durability.
• Direct-fit replacement – no cutting or modifications required.
• Massive 134% increase in core size over the stock unit.
• Includes all necessary installation hardware.
