AEM Performance Cold Air Intake | 2016-2021 Mazda MX-5 Miata 2.0L (21-786C)

Performance Cold Air Intake by AEM Induction

The AEM-21-786C 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 select Mazda MX-5 Miata 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 space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. Attached to the heat shield is an aluminum coolant overflow reservoir that replaces the stock reservoir so that the air intake will fit properly. The air intake tubing 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 flow sensor and PCV 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.
