The Performance Cold Air Intake System AEM-21-786C produces torque and horsepower gains by replacing your vehicle's restrictive factory air intake housing and air filter.
Designed, tuned, and dyno-tested, this air intake system fits select Mazda MX-5 Miata models.
The system allows air to enter through an oversized AEM Dry flow synthetic washable air filter for outstanding filtration, air flow, and performance.
Located in the original air box space, the air filter is protected by a heat shield designed to reduce intake air temperature and increase horsepower.
An aluminum coolant overflow reservoir is attached to the heat shield, replacing the stock reservoir for proper air intake fit.
Constructed from mandrel-bent aluminum, the air intake tubing features a durable gunmetal gray powder coated finish.
Developed to accommodate the engine's factory emissions control devices, including the mass air flow sensor and PCV hose, the tapered cylinder shaped AEM Dry flow 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.
Installation of the air intake system is easy with commonly available tools.
Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
