AEM 14-15 Mazda 3 2.0L L4 - Cold Air Intake System

The AEM 21-765C Performance Cold Air Intake System replaces the vehicle's restrictive factory air filter and air intake housing to produce horsepower and torque gains. It is designed, tuned, and dyno-tested for specific Mazda 3 models. Air enters through an oversized AEM Dryflow synthetic washable air filter, which is relocated to the driver-side wheel well to reduce intake air temperature. The intake tubing is constructed from mandrel-bent aluminum with a durable gunmetal gray powder-coated finish. It accommodates factory emissions control devices, including the mass air flow sensor and crank case breather hose. The oil-free, synthetic Dryflow filter media lasts up to 100,000 miles before cleaning. The system is easy to install with common tools and is backed by AEM's Lifetime Limited Warranty. It is street legal in most states but not in California or states adopting California Emissions Standards.
