Show original supplier description
The AEM 21-533P Performance Cold Air Intake System is a significant upgrade for 2005-2006 Chevrolet Cobalt owners looking to enhance their vehicle's performance. By relocating the air filter to the passenger-side wheel well, this cold air intake system effectively reduces intake air temperatures. This temperature reduction directly translates into increased horsepower and torque, particularly noticeable during spirited driving or daily commutes. The system utilizes an oversized AEM Dryflow synthetic washable air filter, ensuring exceptional airflow while maintaining robust filtration to protect your engine. The intake tubing is constructed from mandrel-bent aluminum and features a durable, mirror-polished powder-coated finish that not only enhances the aesthetics of your engine bay but also withstands the demands of daily driving. The AEM 21-533P is designed to integrate with your vehicle's factory emissions control devices, including the mass air flow sensor, ensuring compliance with regulations. It is street legal in all US states and has a CARB EO Number of D-670-15. The system includes all necessary mounting hardware for a direct fit. Customer feedback indicates significant improvements in throttle response and overall engine performance, with users reporting a noticeable difference in power, especially during acceleration.
