Description
The AEM 21-781DS Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Mercedes Benz CLA250 models. Air enters the system from the factory fresh air inlets, through replacement air ducts and into a roto-molded, aerodynamic AEM air box containing an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. This air intake system was developed to accommodate the engine's factory emissions control devices including the ECU. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools.
Features & benefits
- Precision-tuned and dyno-validated to enhance throttle response, sharpen acceleration, and improve overall engine efficiency, helping maximize horsepower and drivability.
- Creates a deeper, more aggressive induction tone that highlights the intake system’s improved airflow.
- Features low-restriction intake tubing that increases air velocity and high-volume airflow for maximum performance gains.
- Equipped with a long-life, high-capacity air filter capable of up to 100,000 miles before servicing (depending on driving conditions), reducing maintenance while maintaining strong, clean airflow.
- Utilizes washable, reusable, oil-free synthetic filter media that preserves airflow efficiency, traps harmful contaminants, and provides long-term value over disposable filters.
