These kits are a real nice upgrade from the factory look under your hood. Not only that, they allow for replacing the stock turbo with an aftermarket turbo, so you can unleash the beast that is the 6.7L Ford Powerstroke. Our kit was built using 4” diameter tubing w/smooth bends to utilize airflow, which helps to maximizes the performance you can get out of your truck with supporting mods. Choose a color to powder-coat your own kit to stand out from the crowd. GDP kits come in either raw or black powder-coat and include an oversized S&B 7-layer filter, dry or oiled.
