M133 Air Intake System

The Weistec M133 Air Intake System is engineered to minimize restriction within your vehicle's intake system, preserving the advantages of the factory air box, including its substantial cold air inlet and integrated ECU mounting. With an inner diameter of 5 inches, the filter adapter is almost twice the size of the stock component, facilitating a significant improvement in airflow and an increased flow area. The system's subtle appearance ensures it looks stock to the casual observer. This air intake system delivers substantial gains throughout the powerband, resulting in noticeably improved performance and acceleration compared to the factory intake. Key features include an increase of 5 to 15 horsepower and 5 to 15 lb-ft of torque, along with improved turbo response. For optimal results, Weistec recommends combining this intake with their Weistec ECU flash. All necessary hardware is included for a simple bolt-on installation. This air intake system is compatible with the following Mercedes-Benz models equipped with the M133 2.0L engine: A Class W176 (2014-2018) A45 AMG, CLA Coupe C117 (2014-2019) CLA45 AMG, and GLA Class X156 (2014-2020) GLA 45 AMG.
