Maximize the performance of your Duramax L5P with the aFe Power Momentum HD intake system. Engineered for maximum airflow and debris filtration, this system features a CAD-designed, roto-molded housing made from black cross-linked polyethylene (XLPE) to resist heat soak. A built-in clear sight window allows for quick filter inspections without disassembling the airbox. The system is designed around a massive Pro 10R performance air filter, utilizing 10 layers of progressive cotton media to achieve 99.59% cumulative efficiency and a flow rate of 1,000cfm. This setup outflows the factory intake by up to 70%.

• Pro 10R Media: 360-degree radial flow filter with 10 layers of cotton gauze and reinforced metal wrapping to prevent collapse.
• Precision Engineering: Dyno-tuned, roto-molded intake tube maintains factory fan clearance and optimizes air velocity.
• Simplified Installation: Patent-pending filter-to-housing interface reduces part count for a direct bolt-on fit with no cutting or drilling required.
• Heavy-Duty Hardware: Includes premium clamps and a urethane plug for blocking the auxiliary air inlet if desired.
• MPN: 50-74008
