The AFE 51-74001 Pro Dry S Momentum HD Intake System is designed for your 2001-2004 GM 6.6L Duramax LB7 using the 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 Dry S 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.
Roto-mold Tube
This System uses a C.A.D designed, dyno-tuned, roto-mold intake tube to achieve maximum power gains while maintaining a perfect fit.
Huge PRO Dry S Performance Air Filter
This Momentum HD is designed around a massive PRO Dry S performance 360 degree radial flow air filter with 3-layers of progressive synthetic media providing 99.2% cumulative efficiency. 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.
Premium Hardware
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.
Proven Results
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.
Features:
- Pro Dry S Oil-Free Filter
- Outflows Factory Intake By 32%

Less than a week of use and peeling
Color: Black (Passcase), Color: Black (Passcase)
I got this as a gift for my husband and he used it for less than a week and the edges are already peeling. It seems more plastic than real leather. Very disappointing for the price. Would not expect this from Carhartt as their quality is typically very good.

New wallet
Everything is very nice, but. Only carries about 60 % of what I carry with my old wallet.
I also know that wallets need breaking in, but the slots were so tight it took dexterity and strength to slide in and remove a card.
Why don't I send in for a refund? There is no criteria to get a refund that applies. It is beautiful leather, great stitching and overall a great product. Maybe registration it.
