Unlock Hidden Power with Banks Ram-Air

Upgrade your 2004-2005 Chevy or GMC 6.6L LLY Duramax with the industry-leading Banks Power Ram-Air Intake System. Engineered to eliminate the restrictive factory air box, this system delivers a massive increase in airflow, resulting in gains of up to +39 hp and +69 lb-ft of torque. By reducing exhaust gas temperatures (EGTs) and minimizing smoke, you ensure your engine runs cooler and more efficiently under heavy loads.

Precision Engineering & Design

• CAD-Designed Housing: Enclosed cold-air box prevents hot underhood air from robbing power.
• Superior Flow: Outflows stock and competitor intakes by up to 35 percent.
• Rigorous Testing: Validated through flowbench, dyno, and real-world on-vehicle testing for guaranteed performance.
• CARB Compliant: Features EO: D-161-146 for emissions legality.

Unlike "filter on a stick" designs that pull in heat, the Banks Ram-Air system utilizes a high-capacity, oiled filter element housed in a custom-molded air box to ensure only the coolest, densest air reaches your turbo. Whether you are towing, racing, or daily driving, this intake provides the throttle response and reliability you demand. Installation is straightforward, utilizing factory mounting points for a clean, professional look. Experience the difference of premium engineering with GGCRACING.
