AEM Induction Cold Air Intake System (21-750)

Description

The AEM 21-750 Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicles restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Audi A4 and A5 models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box location and can optionally be protected by an AEM embossed heat shield which is designed to reduce intake air temperature and increase horsepower. This air intake system was developed to accommodate the engines factory emissions control devices including the mass air flow sensor. 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 AEMs 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.
