The Sinister Diesel Cold Side Charge Pipe and Intake Elbow Kit for the Powerstroke 6.0L connects the intercooler to the intake manifold. This upgraded pipe is larger in diameter and has smooth mandrel bends to increase air flow velocity to improve power and lower EGTs. The Sinister Diesel Cold Side Charge Pipe Kit is also more durable, being made from 6061 Aluminum alloy and connected with Sinister Diesel's 4-ply silicone boots that are rated up to 400psi. Sinister's Intercooler and Intake Elbow Pipes are masterfully TIG welded and powder-coated Sinister Blue for a beautiful under-hood look.
