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%

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all.
The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day.
They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable.
Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
