This air intake system out-flowed the factory intake by 31%. Includes a durable 18 gauge, powder-coated heat shield; this air intake system features a washable/reusable conical air filter that improves airflow for increased horsepower and torque. Heat shield requires little or no assembly and the filter is constructed with 100% polyurethane for long life and multiple cleaning cycles. aFe (advanced FLOW engineering) spends countless hours with each and every vehicle to ensure that their intakes produce the most horsepower possible. Each intake is dyno tested over and over to ensure their design, air filter, and technology creates the best environment for the most power and torque. aFe uses their special high-flow conical air filters that allow the most possible air flow without letting in contaminants. Each intake produces a deep and throaty sound and outflows the factory intake by an average of 30%!
