The AEM 21-750 Performance cold air intake for Audi A4 and A5 2.0L applications replaces the factory air filter and intake housing with a system tuned and dyno-tested for specific models. It uses an oversized Dryflow synthetic, oil-free washable filter that can go up to 100,000 miles between services, and was designed to accommodate factory emissions controls. An optional embossed heat shield reduces intake temperatures and AEM backs the system with a lifetime limited warranty.
