Description

The AEM 21-640C Performance Cold Air Intake System is engineered to deliver horsepower and torque gains by optimizing airflow to your engine. It replaces your vehicle's stock air filter and intake housing with a more efficient design. This system is specifically designed, tuned, and dyno-tested for compatibility with select Mazda MX-5 and MX-5 Miata models. The intake utilizes an oversized AEM Dryflow synthetic washable air filter, which offers outstanding airflow and filtration. The filter media is oil-free and can last up to 100,000 miles between cleanings, depending on driving conditions. The intake tubing is constructed from durable, mandrel-bent aluminum with a gunmetal gray powder coat finish for a clean aesthetic and lasting performance. This design ensures it accommodates the engine's factory emissions control devices, including the mass air flow sensor. Key specifications include a "No Tune Required" design, ensuring a straightforward installation process without the need for engine computer reprogramming. The filter type is dry, and the tube material is aluminum. The AEM 21-640C cold air intake system is backed by AEM's Lifetime Limited Warranty. It's important to verify the vehicle applications to determine the emissions legal status for your specific region, as some AEM intakes may not be legal for sale or use in California and other states adopting California emission standards.
