The Banks Power 47172 Ram-Air Intake System for your GM 6.6L Duramax is engineered to deliver cool, dense air to your engine helping with power, fuel economy, and overall engine efficiency. Designed using a proven test-first approach, this intake system focuses on airflow, air density, and long-term reliability without triggering fault or error codes.
Proven Engineering & Testing
- Designed in CAD software and analyzed through airflow simulations
- Validated on a flowbench after hardware prototyping
- Tested on-vehicle in real-world conditions
- Density-tested against stock intakes
Banks Ram-Air is designed to:- Duct cooler outside air into the system
- Minimize restriction and pressure loss
- Preserve air density as air travels to the turbo
Its enclosed cold-air housing, large inlet, and streamlined internal design help prevent hot engine-bay air from robbing power.
Built for Real-World Use:
Banks-exclusive 5-inch bellows allows the intake to flex with engine movement, helping prevent component damage and extending service life, an often overlooked detail in the intake design.
Features:
- Helps engine run cool
- Outflows stock up to 47%
- Prevents component damage
- Accommodates engine movement
- Extensively tested & validated
- Reduces exhaust gas temps (EGTs)
- Giant filter maximizes high-flow filtration
- Inhales cooler outside air for more power & MPG
- Extends service life and requires fewer cleanings
- Enclosed housing keeps out hot, power-robbing engine air
