204Denali Posted February 26, 2005 Report Share Posted February 26, 2005 I am not sure what year trucks have this but mine does and its a 04. On the passenger side valve cover, at the front part of the cover near the fan there is a metal tube on top. This tube connects to the intake right behind the throttle body. Anyway my Kenne Bell instructions say nothing about it. Now when you swap the valve covers you now have the tube on the drivers side next to the fire wall. What is everyone with KB's doing with this? I am assuming that it is a breather... I was just thinking of plugging the end on the manifold and adding a filter to the metal tube on the valve cover. Someone please help.
