11-16 Powerstroke 6.7 Hot & Cold Side Kit

Does this take the place of the plastic box upper intake on a 12 f250

This only replaces the plastic intercooler tubing from intercooler to the throttle valve, and the hot side repleaces the metal intercooler tube towards the rear. If you need to replace the plastic box directly on top of the engine this is the link for the replacement plastic manifold:

I also have a kit from Pusher Intakes but you would need the 15+ Turbo for the Pusher kit, if you have dual inlet 11-14 Turbo that kit would not work. Here is a link to it: 11-16 Powerstroke 6.7 Pusher Intake System – RPI Diesel
