Enhance your Mazda MX-5 Miata's performance with the AEM Induction 21-640C Cold Air Intake System. Designed specifically for 2006 to 2009 models, this system replaces the factory air filter and intake housing to deliver increased horsepower and torque. The oversized AEM Dryflow synthetic washable air filter ensures outstanding airflow and filtration, contributing to improved engine response and acceleration. Relocated within the front bumper area, the air filter reduces intake air temperature, which enhances power output and engine efficiency. The mandrel-bent aluminum intake tubing, finished with a durable gunmetal gray powder coat, provides a smooth airflow path that complements the vehicle's existing emissions control devices, including the mass air flow sensor. This system is engineered and dyno-tested to optimize performance while maintaining compliance with EPA standards, and it is backed by AEM's Lifetime Limited Warranty. The synthetic filter media allows for up to 100,000 miles of use before cleaning, depending on driving conditions, making it a reliable upgrade for enthusiasts seeking consistent power gains. Please verify vehicle application and legal status in your state, as some AEM intakes are not California legal. Improve your MX-5 Miata's throttle response and horsepower with this high-quality, performance-oriented cold air intake system, engineered to deliver both efficiency and durability for years of driving enjoyment.
