Looking for a kit that has it all? Featuring a mandrel bent 4 inch intake tube for massive air flow gains, HSP's signature heat shield box eliminating unwanted hot air entering the cold air intake. For every 1 degree increase of intake air temperature will result in a 3hp loss. This kit also features HSP's high flow turbo mouthpiece that out flows any ported mouthpiece on the market. It will also include HSP's hot side and cold side intercooler piping.

The factory intercooler tubing on 2001-2004 Duramax trucks is very restrictive and failure prone. The factory intercooler tubing is only 2.25 inch in diameter and has a 90 degree boot at the intercooler that is prone to failure. With this routing there is a possibility of the hot side intercooler tube rubbing on the power steering line, causing the line to rub a hole in the tube resulting in a boost leak.

HSP's solution to this problem is to run the hot side tube directly into the intercooler using race proven 5 layer silicone boots resulting in lower temperatures, better air flow, and added clearance in tight places. To help get the exhaust gases out of the engine, this kit includes our factory replacement 2 inch up pipes.

Our up pipes use .120 inch wall tubing with the toughest bellows on the market to ensure they last as long as your truck. When it comes to styling we have included our forward facing thermostat housing with coolant return to help keep your IHI turbo running cool. Is your factory coolant tank starting to show its age? Also included is our factory replacement coolant tank to keep your engine bay looking good. Our coolant tank features an all aluminum design with a incorporated low coolant sensor.
