Improve turbocharger efficiency with the Banks Monster-Ram Turbo Inlet Elbow. Engineered specifically for 2017-Current Chevrolet Silverado HD and GMC Sierra HD trucks equipped with the 6.6L Duramax L5P, this high-flow inlet elbow delivers substantially greater airflow to the turbocharger without the destructive turbo surge often associated with oversized aftermarket inlet designs.

After more than a year of development, Banks created a larger, smoother turbo inlet that increases compressor air density while maintaining stable airflow characteristics. The result is 11% lower turbo drive pressure, a 23% increase in Gulp Capacity™, a 17% larger inlet opening, and 11.9% greater mass airflow than the factory turbo inlet. These improvements help reduce turbo shaft speed, improve throttle response and promote longer turbocharger life.

Manufactured from high-quality cast aluminium and finished in a durable Banks Red powder coat, the Monster-Ram Turbo Inlet retains the factory PCV geometry for seamless installation and emissions compliance. It works with both the factory air intake and all compatible Banks Ram-Air Intake Systems, making it an ideal upgrade whether you're keeping the stock intake or building a complete Banks induction package.
