AEM 21-485R Red Cold Air Intake System

Unlock your Mazda RX-8’s performance potential with the AEM 21-485R Cold Air Intake System, engineered to deliver noticeable gains in horsepower and torque. Designed, tuned, and dyno-tested specifically for RX-8 models, this system replaces the restrictive factory air intake assembly with a high-flow setup for improved engine breathing. Air enters the system through an oversized, oil-free AEM Dryflow synthetic air filter that offers superior filtration and airflow. The filter is strategically positioned above the passenger-side wheel well to help draw in cooler air, enhancing combustion efficiency and power output. The intake tube is constructed from mandrel-bent aluminum and features a durable red powder-coated finish, complete with gradually expanding inlet pipes to optimize airflow velocity. Designed to work with factory emissions equipment, including the MAF sensor and breather hoses, this system offers a seamless upgrade and is backed by AEM’s Lifetime Limited Warranty.
