this is my first time doing this. Do i need to remove the egr spacer from my stock upper intake and install it in the Explorer upper intake?
how can i tell if it has an internal egr?
how do the spacers come off.. im having a difficult time removing the spacer..ive tried to hammering it off and sticking a screwdriver in between the plenum and spacer.. do i have to remove the 4 really long screws first?
how can i tell if it has an internal egr?
