HSP Max Flow Turbo Inlet Mouthpiece for 2004.5–2010 Chevrolet / GMC Duramax LLY / LBZ / LMM (for HSP 4.5" Intake)

The factory turbo inlet mouthpiece not only lacks style - it also restricts airflow and limits your engine’s power potential. The HSP Max Flow Turbo Inlet Mouthpiece fixes these issues with a cast-aluminum, CNC-machined design built for performance, durability, and improved sealing. Featuring an integrated O-ring flange to keep unfiltered air out and a 1/2 IN NPT port in the PCV location, this mouthpiece is engineered to pair perfectly with an HSP 4.5" Cold Air Intake for maximum flow.

Included Components

• 1x 4.5IN Max Flow Mouthpiece
• 1x 1/2IN NPT Plug
• 1x 4.5IN Straight Boot (for HSP Intake)
• 2x 4.5IN Stainless Steel T-Bolt Clamps

Special Fitment Notes

• This mouthpiece will not fit with factory intakes.
• For use with aftermarket 4" intakes, see part number 003-4-HSP.
• This product requires a PCV reroute if one is not already installed (recommended: 003-1-HSP).
• 2004.5–2005 models require a 2006–2007 style intake, and the MAF sensor must be rescaled through tuning.
