The OEM turbo coolant feed port on the upper radiator pipe from the thermostat housing will interfere with the larger WCFAB Turbo Intake in this Kit. You MUST use a WCFAB Billet forward-facing thermostat housing Kit or Wehrli Custom Fab Modified OEM Pipe. Billet Coolant Port Block Off Plugs DO NOT allow enough room for clearance on LB7 Models.
