2011-2012 Duramax Max Air Flow Bundle (583-1-HSP)

Fits

For every 1° increase in intake air temperature will result in a 3hp loss. This kit also features HSP's 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. Featuring 3" mandrel bent hot side and cold side tubes with a max flow Y-bridge and turbo mouthpiece. 

The factory hot side intercooler tube on the Duramax is notorious for failure. The two-piece design from the factory has crimped-on boots that have a tendency to fail under heat and pressure, it's only a matter of time before it leaves you stranded on the side of the road. The factory cold side also has its limitations and is made of plastic with an unreliable clamping system.
