Banks Power Monster-Ram Turbo Inlet 2017-2026 Chevy/GMC 2500/3500 6.6L Duramax L5P

Upgrade your 2017-2026 Chevy or GMC 2500/3500 with the 6.6 L Duramax L5P engine using the Monster-Ram Turbo Inlet (42792-R). This high-performance inlet system is engineered to vastly improve airflow, reduce turbo drive pressure, enhance throttle response, protect turbo life, and maintain full 50-state emission compliance.

Key Features & Benefits

• Improved throttle response thanks to optimized flow design.
• Reduced turbo shaft speed and drive pressure for increased turbo longevity.
• 11% lower turbo drive pressure compared to stock.
• 23% greater “Gulp Capacity™” (inlet volume) to support heavy-duty use.
• 17% larger turbo inlet size than the factory elbow.
• Cast aluminum construction for strength and durability.
• Finished in red powder coat or available in raw aluminum for custom coating.
• Maintains PCV geometry and emissions hardware for full compliance (CARB-EO D-161-158 for 2017-2024, pending 2025-26).

Why It’s Better

The Monster-Ram Turbo Inlet isn't just a larger elbow — it's a precisely designed airflow solution built to optimize your Duramax. With over 18 months of development and more than 40 prototypes tested, this inlet improves airflow into the turbo while controlling compressor surge. The smoother path and optimized volume result in faster turbo response, cooler air charge temps, and enhanced turbo life — ideal for heavy duty usage, towing, or performance builds.
