The AFE 54-74001 Pro 5R Momentum HD Intake System is designed for your 01-04 GM 6.6L Duramax LB7 using the most up-to-date engineering tools and techniques to provide you with the perfect blend of power and protection. From the one-piece sealed housing to the massive PRO 5R air filter and premium hardware, we spared no expense to give you the best intake on the market.
Unique One-Piece Housing: The smooth one-piece sealed housing with auxiliary air scoop is used to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. A urethane plug is also included for those cold weather applications where you want to block the auxiliary air scoop. A large, stainless steel plate is used for an aggressive style.
Huge PRO 5R Performance Air Filter: This Momentum HD is designed around a massive PRO 5R performance 360 degree radial flow air filter with 5-layers of progressive cotton gauze oiled media providing 98.6% cumulative efficiency and maximum flow. The unique air filter to housing interface (PATENT PENDING) allows for maximum filter size which increases the available air volume while simplifying the installation process. The air filter is wrapped in reinforced metal providing maximum strength to prevent filter collapse.
This System uses a C.A.D designed, dyno-tuned, roto-mold intake tube to achieve maximum power gains while maintaining a perfect fit.
Premium stainless steel T-bolt clamps are used to securely mount the high flow air filter to the 1-piece airbox. Momentum HD intakes are designed with fewer parts for a quick and simple installation.
After a rigorous design and testing phase, the results are in. The Momentum HD intake system outflowed the factory intake by 32% and produced 24 additional horsepower and 44 lbs. x ft. torque.
Note: This intake system is not CARB exempt at this time and is not legal for sale in California or use on vehicles registered with the California Department of Motor Vehicles.
