aFe 50-70070D Momentum HD Cold Air Intake System with Pro DRY S Filter

The aFe Momentum HD Cold Air Intake System with Pro DRY S Filter is engineered to deliver maximum performance gains for diesel engines. This complete sealed intake system features a patented one-piece housing design with dyno-tuned intake tubes that outflow the factory intake by 20%, delivering measurable airflow of 360 CFM at 7" H2O.

Performance You Can Feel:

• Dyno-proven gains up to +11 horsepower and +21 lb-ft torque
• One-piece sealed housing constructed of heat-resistant cross-linked polyethylene (XLPE)
• Patented filter-to-housing interface (US PAT 9440175) for easy installation and maintenance
• Incorporates factory air scoop inlets plus optional auxiliary air inlet for maximum airflow
• Large clear sight window allows hassle-free filter inspection without disassembly

Pro DRY S Air Filter Technology:

The system includes a massive 9-inch tall, 360-degree radial flow air filter with a 5-1/2" flange, featuring oil-free Pro DRY S media with three layers of progressive synthetic material. This media provides 99.2% cumulative filtration efficiency while requiring no oils for maintenance—making it ideal for street use. The inverted top design maximizes filter surface area for longer service intervals, while reinforced metal construction prevents filter collapse under demanding conditions.

Premium Components and Installation:

Each kit includes dyno-tuned XLPE intake tubes that are heat soak resistant and extremely durable, along with premium stainless-steel T-bolt clamps and silicone couplings for secure, long-lasting installation. The simplified design uses fewer parts and factory mounting points for straightforward installation. Kit includes air filter, sealed air box, straight tube, curved tube, couplings, clamps, and all necessary hardware.
