AEM Performance Cold Air Intake | 2015-2018 Mazda 3 2.0L (21-773C) AEM Induction Systems

Performance Cold Air Intake by AEM Induction

The AEM 21-773C 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 Mazda Mazda3 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 airbox space and is protected by a heat shield which is designed to reduce intake air temperature and adapts to the factory cold air scoop. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the mass air sensor and engine breather hose.

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.
