Show original supplier description
The Weistec M276 Intake System is engineered to significantly increase airflow to your Mercedes-Benz M276 twin-turbocharged engine. With 225% more airflow area than the stock system, it allows the engine to produce more power, especially when running higher boost levels, tuned, or equipped with upgraded turbochargers. Constructed with high-precision laser scanning and manufactured in the USA, this intake system boasts durable materials. The air filters utilize a 4-ply lightly oiled cotton media for minimal restriction and effective filtration. Airbox lids combine a 0.03" 304 stainless steel base with a carbon fiber top layer for a refined look and easy servicing. The core support adapters are made from 80 durometer silicone, ensuring an unrestricted connection to the air intake ducts, avoiding the restrictive bellows design found in some competitor adapters. Key features include 100% bolt-on installation, making it a straightforward upgrade. It is also 100% serviceable, designed to reduce the wastegate duty needed for higher-than-stock boost levels, and substantially increases airflow over OEM. This part fits various Mercedes-Benz models including the C400 4Matic (2015), C43 AMG 4Matic (2017-2021, 2019-2020 Base), and C450 AMG 4Matic (2016), all equipped with the M276 V6 engine.
