The AFE 50-74001 Pro 10R 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. This intake system is superior in every way. From the one-piece sealed housing with a built-in sight window to the massive 1,000 cfm 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, clear sight window is used for a hassle-free filter inspection.
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 10-Layer Pro 10R Performance Air Filter:
The Momentum HD is designed around a massive 1,000 cfm 360 degree radial flow performance air filter with 10-layers of progressive cotton gauze oiled media providing 99.59% cumulative efficiency (independently tested). 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 and a 2-ply reinforced silicone hump coupler at the turbo is used for strength and durability while also providing the most secure installation available. 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 outflows the factory intake by 32% and produces 24 additional horsepower and 44 lbs. x ft. torque.

Comfortable and Easy to Wear Daily
Size: 2 Little Kid, Color: Navy/Blue
My daughter has been wearing these navy/blue shoes since the weather has been less rainy and more sunny. They are great for outdoor play, especially on days when it's warm outside. The knit mesh upper keeps her feet from overheating, and the cushioned insole feels supportive without being stiff. At size 2, the fit is accurate and the width runs a bit roomy, which gave her some growing room without feeling loose.
The slip-on design with elastic laces and pull tabs is a real plus. She can get them on and off without any help, which she loves. The shoes are light enough that she barely notices them during long active days. My one small complaint is that the sole feels more like firm foam than rubber, so they can be a little slippery on smooth indoor floors.
For the price, these deliver solid everyday value. They look good, hold up well to regular use, and my daughter reaches for them first most mornings.
Pros:
- Breathable mesh keeps feet cool
- Easy slip-on design with elastic laces and pull tabs
- Lightweight and comfortable for all-day wear
- Accurate sizing with a roomy width
- Durable for the price
Cons:
- Sole can be slippery on hard smooth surfaces
- Limited outsole grip compared to rubber-soled shoes

Great kids' shoe — easy on, comfy all day
Size: 3 Little Kid, Color: Pink/Lavender
My kid has been wearing these for a few weeks now and I'm genuinely impressed with how well they've held up. The knit mesh upper keeps feet cool and comfortable during long days at school and outdoor play, and the cushioned EVA midsole does a great job absorbing impact.
What really won me over is the slip-on design with elasticated laces and dual pull tabs — my child can put them on and take them off completely independently, which is a huge win. The fit is snug but not tight, and they run a bit roomy in width, which is great for kids with wider feet or those who need a little growing room.
At $32, the quality feels solid for the price. Lightweight, breathable, and easy to wear — these check all the boxes for an everyday kids' shoe.
