Engineered specifically for 3rd Generation (2007.5–2009) Dodge Ram 2500 and 3500 trucks powered by the 6.7L 24-Valve Cummins turbo diesel, the Volant Closed Box Cold Air Intake System (VP168676 / 168676) delivers thermal isolation and heavy-duty filtration. This configuration discards the restrictive OEM airbox and corrugated rubber ducting in favor of an aerodynamic, smooth-bore induction tract engineered to supply cool, dense ambient air directly to the Holset variable-geometry turbocharger (VGT).

The kit centers around Volant's high-density, cross-linked polyethylene (XLPE) fully enclosed airbox, which blocks power-robbing radiant under-hood heat while capturing outside air through high-velocity forward scoops. Inside, the Donaldson PowerCore filter uses fluted synthetic media to trap sub-micron contaminants without requiring filter oils, wash kits, or frequent servicing. The dry fluted architecture prevents surface loading and maintains steady airflow in commercial, agricultural, and high-dust towing environments for up to 100,000 miles.

Key Features & Benefits

• Donaldson PowerCore Fluted Filtration: Advanced dry synthetic fluted media captures 99.97% of airborne dust and soot particles without oil, preventing MAF/IAT sensor contamination and lasting up to 100,000 miles in highway driving conditions.
• Fully Enclosed Thermal Enclosure: Roto-molded XLPE airbox isolates incoming intake air from high engine bay temperatures to lower intake air temperatures (IATs).
• Smooth-Bore Polyethylene Intake Duct: Replaces restrictive factory corrugated ducting and resonator chambers to reduce airflow turbulence and sharpen turbo spool response.
• Direct OEM Sensor Accommodation: Molded sensor mounting pads accept factory Ram intake temperature and pressure sensors for error-free ECM operation without check engine lights.
• Severe-Duty Dust Protection: Specifically engineered to handle severe-duty commercial fleets, gravel haul roads, and heavy trailer towing without premature filter clogging.
• Direct Bolt-On Fitment: Installs in under 60 minutes using basic hand tools, securing straight to factory body mounting locations without drilling or cutting.
