****These are special order and carry a 2-3 week lead time****

HSP Turbo Inlet Max Flow Mouthpiece for 2004.5–2010 Chevrolet / GMC Duramax LLY / LBZ / LMM (for 4” Aftermarket Intakes)

The factory turbo inlet mouthpiece not only lacks style ” it also restricts airflow and limits your engine’s power potential. The HSP Max Flow Mouthpiece solves both issues using a cast-aluminum, CNC-machined design engineered for durability, airflow, and improved sealing. Featuring an integrated O-ring flange to prevent unfiltered air leaks and a ½— NPT port in the PCV location, this mouthpiece ensures that your aftermarket intake system is not held back by a restrictive OEM component. The 4.5— inlet guarantees maximum flow before reducing to your 4— aftermarket intake.
