The AEM 21-721C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Mini Cooper S, S Clubman and John Cooper Works models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space and is protected by a replacement air box with a fully-opened hood scoop which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable black powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor and vacuum line port. The cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions).
Innovation has always been AEM's core competency. As J.C. would say "if you can't make something better, why make it all?" This "make it better" drive combined with our commitment to the sport compact market continues to distinguish AEM from the many company's offering "Me Too" copycat products. Our innovations are inspired by a passion for engineering excellence, being there and getting our hands dirty, the only way to really understand technology enough to make it better. The company continues to lead the way with innovative products that push the envelope of what is possible.
