Performance Cold Air Intake System for Mercedes-Benz C400 / C450 / C43 / GLC43 AMG (M276 V6)

This Cold Air Intake Kit modifies the airflow path and induction acoustics of the M276 engine. The enlarged intake tubes and streamlined internal surface amplify the sound of the turbochargers spooling and the volume of air being drawn into the system. This provides a more pronounced mechanical sound during acceleration and higher RPM loads.

Engineering for the 3.0L Biturbo V6 focuses on replacing restrictive factory components to allow for a higher volume of air. By delivering cooler, denser air to the turbochargers, this kit improves throttle response and provides more consistent power delivery throughout the powerband.

Key Features

• Increased Turbo Acoustics: Enhances audible turbo spool and induction sounds.

• Higher Airflow Volume: Enlarged intake tubes reduce restriction for improved turbocharger efficiency.

• Dry Filtration: Includes a high-flow, washable dry-style air filter for filtration without oiling.

• Thermal Isolation: Features a heat shield designed to block engine bay heat from the intake charge.

• Improved Response: Sharpens throttle sensitivity and mid-range acceleration.

• Durable Construction: Built with materials designed for long-term engine bay heat resistance.

Installation Tip

Unplug the car battery's NEGATIVE GROUND CABLE before installing this product. After the installation is complete, leave the cable disconnected for at least 60 seconds. This allows the vehicle's ECU to reset and calibrate for the increased airflow, which optimizes performance gains and prevents potential check engine light errors. Perform installation on a completely cool engine.
