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 and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
