[QUOTE="HS-MotorsportsDallas, post: 1324708, member: 19010"] I'm going to have to disagree with this statement to a certain extent. The 6.7 does not require a vacuum to keep crankcase pressures in check. There is a huge difference between engines that have a vacuum pump and ones that simply vent to the intake in a diesel application (gas engines are a different animal). It's easy to see my point when you look at how the system works. In order for the engine to pull a significant amount of vacuum via the intake, there must be a restriction of some sort. The only place for there to be a viable restriction is the intake filter itself. Because there is a small amount of restriction caused by a filter, you will naturally get a very small amount of vacuum but it's negligible at most. The only way to get enough vacuum from the intake system to show performance advantages would be to run a more restrictive filter which would net more power loss than running little to no vacuum at all. Hope that helps! [/QUOTE]
