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

Upgrade the sound, airflow, and responsiveness of your Mercedes-Benz M276 3.0L Biturbo V6 with this high-performance cold air intake system. Designed to optimize the intake path, this system increases airflow efficiency while delivering aggressive turbo spool and induction sound under acceleration.

By replacing restrictive factory intake components with enlarged, smooth-flow intake tubes, this system allows a greater volume of cooler, denser air to reach the turbochargers. The result is improved throttle response, stronger mid-range performance, and more consistent power delivery across the RPM range.

Key Features

• Enhanced Turbo Acoustics: Noticeably increases turbo spool and induction sound for a more engaging driving experience.
• Improved Airflow: Enlarged intake tubing reduces restriction and improves turbocharger efficiency.
• High-Flow Dry Filter: Washable, reusable dry-style air filter delivers strong filtration without oiling.
• Heat Shield Protection: Thermal barrier helps isolate the intake from engine bay heat.
• Sharper Throttle Response: Improves acceleration feel and mid-range engine response.
• Durable Construction: Engineered with heat-resistant materials for long-term reliability.

Installation Tip

Before installation, disconnect the vehicle’s negative battery terminal.

This helps optimize performance and reduce the chance of check engine lights. Always install on a completely cool engine.
