Cold Air Intake for Mercedes Benz C43 AMG GLC43 AMG (2014-2021) 3.0T

High-Flow Cold Air Intake for 2014-2021 Mercedes Benz GLC-Class, C-Class

Direct Bolt-On Air Intake System: Replaces the restrictive factory airboxes on the M276 3.0T V6 to lower intake air temperatures, reduce airflow restriction, and optimize combustion efficiency.

The Stock W205 / C253 Airflow Restriction

The OEM Mercedes-Benz intake utilizes corrugated plastic tubing and dense paper filters encased in restrictive airboxes. These plastic components suffer from severe heat soak within the cramped M276 engine bay. The corrugated piping generates turbulent airflow, reducing the velocity of air reaching the twin turbochargers and creating a significant bottleneck during high-load acceleration.

The Engineering Solution

This aluminum alloy cold air intake kit directly addresses factory M276 restrictions. Smooth, mandrel-bent aluminum piping eliminates internal turbulence, maximizing air volume supplied to the turbo compressors. High-flow, reusable conical filters replace the factory paper elements to vastly increase surface area without compromising filtration. To mitigate radiant heat, the kit includes custom-fit heat shields. This ensures the turbochargers ingest denser, colder air, translating to sharper throttle response, consistent power delivery, and enhanced induction acoustics under heavy load.
