Forever lurking, thought I'd give my 2cents on the KKM kit. Installed it two days ago (easy) and already feel and hear the difference. I live at 7500ft. and this filter really lets the 4.0 breathe. The motor now revs quicker and accelerates noticably better. If you have an older explorer, navajo I would definately make this a priority on engine mods.
