Upgrade your Mini Cooper S, S Clubman, or John Cooper Works with the AEM 21-721C Performance Cold Air Intake System, engineered to enhance horsepower and torque. This system replaces the factory air filter and intake housing with a high-flow, oversized Dryflow synthetic washable filter, providing superior airflow, filtration, and performance. Designed, tuned, and dyno-tested to optimize engine output, the intake system features a fully-opened hood scoop and a replacement air box that work together to reduce intake air temperature, increasing power and acceleration. The mandrel-bent aluminum tubing, finished in a durable black powder coat, ensures smooth airflow and long-lasting performance while accommodating factory emissions control devices such as the mass air flow sensor and vacuum line port. The synthetic filter media is oil-free and capable of lasting up to 100,000 miles before cleaning, depending on driving conditions. This system also adheres to EPA standards and includes a CARB EO number, ensuring legal compliance in most areas. Backed by AEM's Lifetime Limited Warranty, the 21-721C is a reliable upgrade for enthusiasts seeking improved engine response and efficiency without sacrificing emissions compliance. Properly fitted, this intake system offers a significant performance boost while maintaining the vehicle's original emission control functionality, making it an excellent choice for daily drivers and performance enthusiasts alike.
