Transform the performance of your 2004.5-2005 GM 6.6L Duramax LLY with the Banks Power 42135 Ram-Air Intake System. This advanced intake system is engineered to deliver unparalleled increases in airflow, air density, and power, making it a top choice for those seeking maximum engine performance. The system features a large cotton gauze air filter that requires fewer cleanings and offers a significant upgrade over the stock's non-reusable paper filter.

At the core of the Ram-Air Intake System is a massive 7-1/8" outlet, streamlined components, and an enclosed cold-air box that effectively blocks hot engine air from entering the intake. This design enables the system to flow up to 57% better than stock systems and 23% better than other aftermarket options. The result? A powerful gain of up to +39 horsepower and +69 lb-ft of torque—beyond what a tuner alone can achieve—alongside improved fuel efficiency and reduced black smoke emissions, indicating more complete fuel combustion.

Banks' innovative 4-1/2" bellows are designed to flex with engine movement, protecting components from damage and enhancing the system's durability. With no risk of triggering fault or error codes and a lifetime warranty on the filter element, this intake system delivers both exceptional performance and peace of mind.

Outstanding Features:

• Superior Airflow: Flows up to 57% better than stock systems, ensuring maximum power and performance gains.
• High-Efficiency Filter: The large cotton gauze filter requires minimal maintenance and outperforms standard filters in durability and efficiency.
• Engine Protection: The enclosed cold-air box prevents hot engine air from entering the intake, while the unique bellows design absorbs engine movement, preventing damage.
• Guaranteed Quality: Includes a no-fault lifetime warranty on the filter element and a 5-Year Limited Warranty on the system, ensuring long-term reliability.

For those looking to push their vehicle's performance even further, consider adding the optional Banks Super-Scoop. This exclusive accessory enhances the Ram-Air Intake System by directing a powerful charge of cool, pressurized air from outside the engine compartment into the air filter housing. The Super-Scoop not only increases power output but also prevents rainwater and debris from entering the intake system. Note that the Super-Scoop is sold separately for those seeking the ultimate performance upgrade.
