The Banks Monster-Ram® Turbo Inlet for the 2017-2026 Duramax L5P is the only intake elbow that outperforms stock without the destructive effects of turbo surge, caused by competitors. More than a year in development, the Monster-Ram® increases air density to the compressor. This results in slower turbo shaft speed and a reduction in time to boost. With slower shaft speeds, throttle response is improved, and turbo life is increased.
Turbo Induction Perfection
With 18 months of development and over 40 prototypes tested, the Banks Monster-Ram® for the Duramax L5P is more than just attractive. It's turbo induction perfection.


The Monster-Ram® fills every millimeter of available space within the L5P's compact V8 layout improving airflow and density at the turbo inlet.
Every facet from inlet and outlet size, orientation and location of the PCV connection, and down to the angle of the ported shroud interface had to be dialed into exact tolerances.

Mass Air Flow has been improved by almost 12% by removing stock restrictions at the turbo inlet all while preventing destructive turbo compressor surge and maintaining emissions compliance.

All other designs we found on the market and tested against, either outflow stock at the expense of your turbo and emission systems, or flow less than stock by the time they are restricted back down with an inferior anti-surge design.


The Monster-Ram®'s propriety design reduces pressure loss by 18.67% at the compressor inlet which results in an impressive 6.01lb/min gain in Mass Airflow verses stock.
This reduces turbo drive pressure by 11% which improves throttle response, time to boost, and increases turbo life.
