AEM cold air intake system for 2005-2008 Audi A4. Upgrading to a cold air intake system provides more horsepower and higher torque for your vehicle. Cold air intake systems relocate the air filter further away from the engine, providing a source of air that is much cooler than a stock intake system. Cold air is dense and compresses into your engine cylinders much more effectively than hot air. The result is massive power improvement, enhanced throttle response and aggressive engine sound. AEM is the leading manufacture for cold air intakes. Reliability and durability have set their products miles ahead of the competition. All AEM intakes are made in the U.S.A and are either C.A.R.B. exempt or pending C.A.R.B. exemption.
Upgrading your vehicle's air intake system to an AEM cold air intake is an easy bolt-on installation. All AEM cold air intakes are sold with all parts necessary for the installation as well as an easy to read installation guide. AEM intakes can increase power and give your engine bay the performance look you?ve been searching for.
