2017–2026 L5P High-Flow Intake Air Horns
Introducing from VIN Specific Enterprises — the first-to-market High-Flow Intake Air Horns, featuring an interchangeable surge guard for the 2017–2026 6.6L L5P Duramax.
Engineered for everything from stock trucks to full-horsepower builds, this system delivers a 22% increase in volumetric airflow and expands from 2.4” to 3.6” throughout the entire intake path, maximizing efficiency and promoting smoother, unrestricted air delivery.
Designed to reduce or eliminate turbo surge caused by high drive pressure to boost imbalances by increasing the max available intake volume at the inlet of the compressor.
Each unit includes a removable, replaceable surge guard, available for varying turbocharger inducer sizes — Stock, 64mm, 65mm, 67mm, and 69mm — and is offered with or without a CCV port, making it an ideal fit for any configuration.
Installation is straightforward and can be completed in about 1 hour with basic tools.
