High-output engines require high-flow crankcase ventilation. More air and fuel going into the cylinder means more blow-by working its way past the piston rings and traveling around your intake system. All that volume needs room to flow, and if you're using a catch can, it better flow well too. Luckily, Mishimoto has created a catch can that meets those needs. Our high-flow catch can utilizes a high-capacity bottom with a 5.3 fl. oz. capacity. The CNC-machined lid includes large, M27 x 2.0 inlets and outlets to let your crankcase breathe. Inside the can is a newly engineered, CNC-machined baffle with integrated filter that lets crankcase gases flow through while filtering out potentially harmful fuel, oil, and water vapors. Like our compact baffled oil catch can, our high-flow catch can and filter are fully serviceable for easy draining and cleaning. The included 3/8? NPT plug in the bottom of the can allows you to drain the can without removing the bottom or attach our available drain kit for even easier servicing. To make this kit direct-fit for your 2003-2007 Ford 6.0L Powerstroke, Mishimoto includes a custom-engineered bracket that bolts to the driver's side frame rail, just behind the wheel well. This mounts the can in an easy to access location that's out of the way of engine components. The 3mm thick steel bracket is gusseted and powder-coated black for the highest strength and resistance to the elements. Also included with this kit is a set of direct-fit nitrile hoses to carry blow-by away from your engine and into the catch can. Of course, all our catch can kits come with Mishimoto's Lifetime Warranty with Accident Protection, and this kit is no exception.
