Engineered specifically as a direct-fit performance upgrade for the aFe Momentum HD cold air intake system (50/51-73004) on 2008 through 2010 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.4L Powerstroke V8 diesel engine, the aFe Dynamic Air Scoop (Part # 54-73004-S) captures high-velocity ram air straight from the front grille.

Constructed from durable, impact-resistant linear low-density polyethylene (LLDPE), this auxiliary scoop forces dense, cool outside air directly into the sealed airbox to reduce intake air temperatures and maximize overall turbo efficiency.

Key Features & Benefits

• Ram-Air Airflow Funneling: Captures high-pressure ambient air from the front grille and forces it directly into the Momentum HD auxiliary intake port.
• Lower Intake Air Temperatures: Helps reduce under-hood heat soak for denser, oxygen-rich combustion charges.
• Durable LLDPE Construction: Impact-resistant, UV-stable rotomolded polyethylene ensures long-lasting under-hood durability.
• Hassle-Free Snap-In Design: Engineered for a secure, direct snap-in installation requiring no cutting or drilling.
