Engineered specifically for 2005 through 2010 Chevrolet Silverado and GMC Sierra 2500HD/3500 trucks powered by the 6.6L Duramax V8 turbo diesel engine (LLY, LBZ, and LMM codes), the Volant Ram Air Intake Scoop (Part # 35066) is designed to capture high-pressure outside air from beneath the front bumper and funnel it directly into the bottom of your enclosed airbox.

Under heavy towing and high-performance operating conditions, standard under-hood airboxes can ingest warm air, elevating intake temperatures and reducing engine efficiency. The Volant 35066 scoop mounts behind the front valance, utilizing vehicle forward motion to force dense, cool ambient air straight to your air filter. Constructed from heavy-duty, heat-resistant rotomolded polyethylene, this bolt-on upgrade integrates seamlessly with Volant closed-box systems or compatible OE airboxes with zero core charge.

Key Features & Benefits

• Ram Air Pressure Boost: Captures high-velocity frontal airflow to force dense, oxygen-rich ambient air directly into the airbox.
• Lowers Intake Temperatures: Reduces air charge temperatures compared to pulling stagnant, heated air exclusively from under the hood.
• Heavy-Duty Rotomolded Construction: Manufactured from durable, cross-linked polyethylene (XLPE) designed to withstand road debris, salt, and extreme weather.
• Direct Bolt-On Design: Mounts cleanly beneath the front bumper using factory fastening points with minimal installation time.
• Zero Core Charge: Brand-new outright accessory upgrade requiring no core deposit or core return shipping.

• Installation Tip: Position the vehicle safely on a lift or use front ramps to access the lower core support and bumper valance area. Align the scoop inlet beneath the front bumper opening and secure it to factory mounting locations. Ensure the upper duct snout mates securely against the lower airbox port to prevent unmetered air leakage.
