It is a full set of charge pipes, except for on the passenger side of the truck this kit goes from the y pipe to the intercooler. On the drivers side the entire pipe is replaced. We can supply block off plates and run the TiAl, or you can run the stock BOVs. The advantage of running the Tial is that if there is any condensation in the intercooler the Tial BOV will discharge it. The Tial is mounted at the lowest part on the charge pipe.
