This Stage 2 cold air intake system outflowed the factory intake by 67%. How this translates into horsepower and torque gains has yet be be determined because the 2011 Ford 6.7L Power Stroke is so new that it does not have enough miles to be dyno. Stay tuned for further updates. Enclosed in a durable 16 gauge, powder-coated heat shield; this air intake system features a washable/reusable conical air filter with Pro5R oiled media that improves airflow for increased horsepower and torque. This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. One-piece heat shield requires little or no assembly and utilizes factory mounting points for easy, no-cutting or drilling installation. The filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.
