HSP Cold Air Intake/Mouthpiece 2004.5-2007 LLY/LBZ

*This Product will ship out in an average of 7 business days for raw and 17 business days for powder coated

The HSP Cold Air Intake Bundle consists of two major parts. That HSP Diesel saw as major power killers and parts that really needed to be changed. So we wanted to start with something that was a good first step for many and most people with the 2004.5-2007 LLY/LBZ Duramax equipped trucks. Our HSP Cold Air Intake Bundle comes with a Cold Air Intake, a VGT Mouthpiece, and all new hardware.

Our Cold Air intake that comes with the HSP Cold Air Intake Bundle also includes a 4 ½” mandrel-bent tubing that provides an extremely consistent and free-flowing path that reduces turbulence and allows for more air to flow. These intakes have been dyno proven to provide an additional 20 Horsepower and 58 pound feet of Torque on average.
Our VGT Intake Mouthpiece is hand fabricated, now what this means and does for you is we are able to make sure that the VGT Intake Mouthpiece has the smoothest transitions possible all while still retaining the factory location. The VGT Intake Mouthpiece also uses an O-Ring seal at the inlet of the turbo, this provides us with the tightest seal possible and prevents any unwanted air from coming in or our fresh air going out. Using HSP Diesel’s VGT Intake Mouthpiece combined with our Cold Air Intake you are able to get the absolute maximum amount of air that the system can offer.

*This turbo mouthpiece that is sold in this kit will give you the ability to reroute your factory PCV system and remove the factory resonator box. Thus eliminating unwanted engine oil gumming up the turbo, and intake system (PCV re-route sold separately see 003-1-HSP)
Pricing: $582.10
