2006-2007 Duramax Max Air Flow Bundle (383-HSP)

Fits

Featuring a mandrel-bent 4.5" intake tube for massive airflow gains, with HSP's signature heat shield Box eliminating unwanted hot air entering the cold air intake. For every 1° increase in intake air temperature will result in a 3hp loss. This kit also features a high-flow turbo mouthpiece. This turbo mouthpiece will give you the ability to reroute your factory PCV system and remove the factory resonator box, eliminating unwanted engine oil gumming up the turbo and intake system. 

The factory hot side intercooler tube is only 2.25" in diameter and has a 90° 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. The solution to this problem is to run the hot side tube directly into the intercooler resulting in lower temperatures, better airflow, and added clearance in tight places.
