Colder air contains more oxygen, enhancing the combustion process. Cold air intake systems from aFe are enclosed in a durable powder-coated heat shield, and use a washable/reusable air filter that provides better airflow than stock. aFe's cold air systems are designed for bolt-on installation, and will work with your car's electronics and sensors (some models come with a built-in MAF pad). Redirect and increase air flow for better torque, horsepower and gas mileage!
