The AEM-21-786C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing, giving your car outstanding air flow, filtration, and performance. The AEM Dry flow synthetic washable air filter is located in the original air box space; it's protected by a heat shield which reduces intake air temperature and increases horsepower. Attached to the heat shield is an aluminum coolant overflow reservoir that replaces the stock reservoir for a proper fit. The air intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. The tapered cylinder shaped AEM Dry flow 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. Not CARB approved and cannot ship to an address in the state of California or Colorado.
