Installed at 1100 miles and current mileage is 8918 pic was taken Friday the 11th and no BG, seafoam, or any other top end cleanings done. In fact the intake runners look exactly the same as they did when I installed the 6.2 manifold at that 1100 mile install of the catch can. It's an Original RX can with clean side seperator. The back of the Throttle body was also clean as new no film or nothing at the throttle blade. Very impressed and is worth every dime I spent on this upgrade as I drive pretty aggresive and now It has a Magnuson TVS installed this weekend. I have a 12oz bottle I empty the oil and water into and its some nasty acidic smelling crap. My truck is a 14 with a 5.3
