AEM Cold Air Intake System for 2006-2009 Mazda MX-5 Miata (2.0L) - 21-640C

Fits 2006-2009 Mazda MX-5 Miata models with the 2.0L L4 engine. The AEM 21-640C Cold Air Intake System replaces the restrictive factory air box and intake housing to improve airflow and throttle response.

Engineered for specific MX-5 Miata applications, this system relocates the air filter to the driver-side front bumper area. This placement ensures the engine draws in cooler, denser outside air rather than heated air from the engine bay, resulting in measurable gains in horsepower and torque. The intake tube is constructed from mandrel-bent aluminum for smooth internal airflow and is finished in a durable gunmetal gray powder coat. The system is designed to accommodate all factory emissions equipment, including the original mass air flow (MAF) sensor.

• Dryflow Filtration: Includes an oversized, oil-free synthetic Dryflow air filter that is washable and reusable for up to 100,000 miles between cleanings.
• Mandrel-Bent Tubing: 2.0L-specific aluminum intake tube ensures consistent diameter through bends to reduce turbulence.
• Vehicle-Specific Tuning: Dyno-tested to ensure optimal performance gains without triggering check engine lights.
• Finish: Corrosion-resistant gunmetal gray powder-coated finish.
• Included: Intake tube, Dryflow air filter, couplers, and all necessary mounting hardware.
• MPN: 21-640C
