Max Flow Intake Mouthpiece For 2004.5-2010 Chevrolet And GMC LLY / LBZ / LMM Duramax With HSP 4.5IN Intake - HSP Diesel - 003-HSP

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.
