air filter questions and fleece 2nd gen swap
 

Got an 09 6.7 g56 and im really looking at the fleece 2nd gen s463 swap. Anybody have this on a truck like mine and tow and how do you like it? Also it looks like it comes with an s&b filter? And last it looks like its just a open filter with no box around it. How quickly do those get dirty and will a filter wrap help? The truck is a welding rig and i pull a 40 foot fifth wheel all over the country not looking to do any major fuel upgrades. About to get rid of smarty and do efi and a lift pump probably. Stock injection pump and stock injectors. Thanks ahead for any information
