2017-2019 Duramax L5P aFe Power Momentum HD Cold Air Intake System w/ Pro 10R Filter (50-74008)
Unique One-Piece High Quality Housing w/ Sight Window:
A custom CAD designed roto-molded housing made from heat soak resistant material eliminates the use of multiple components and ensures the coolest air intake charge available. A large clear sight window allows for filter inspection without removal of the air box. The roto-molded housing is made out of black cross-linked polyethylene. A urethane plug is also included if you wish to block off the auxiliary air inlet.
High Quality Tube:
This system uses a high quality plastic CAD designed, dyno-tuned, roto-molded designed intake tube to fit with the stock mechanical fan and achieve maximum power gains while maintaining a perfect fit.

The Momentum HD intake is designed around a massive 1,000 cfm performance 360 degree radial flow air filter with 10-layers of progressive cotton media providing 99.59% cumulative efficiency (independently tested). The unique air filter to housing interface 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
