HSP Diesel Max Flow Intake Mouthpiece For 04.5-10 Chevrolet And GMC LLY/LBZ/LMM Duramax With 4 Inch Aftermarket Intakes Polar White

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 1/2 inch 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 inch inlet guarantees maximum flow before reducing to your 4 inch aftermarket intake.
