The BD Diesel Performance Crank Case Vent Filter Kit for the Ford 6.0L and 7.3L Power Stroke applications reduce crankcase oil vapor that passes through the crankcase vent and contaminates the intake system. Oil Vapor residue reduces turbocharger and intercooler efficiency and also deteriorates the silicone boots causing them to balloon and blow off. The Crank Case Vent Filter Kit prevents all of these issues, and includes everything you need for a professional installation, including all hardware and clamps. Installation time takes just a few hours.
