Engineered specifically for 3rd Generation (2007.5–2009) Dodge Ram 2500 and 3500 trucks powered by the 6.7L 24-Valve Cummins turbo diesel engine, the Volant Closed Box Air Intake System (16867 / VP16867) delivers cold, dense ambient airflow while insulating the induction tract from high engine bay heat soak. The system replaces the restrictive factory air cleaner and corrugated rubber intake ducting with an aerodynamic, smooth-bore induction assembly that feeds high-velocity air directly to the Holset variable-geometry turbocharger (VGT).

At the core of this system is Volant's high-density, cross-linked polyethylene (XLPE) sealed airbox, designed to pull cool air through high-velocity ducts while completely blocking power-robbing radiant under-hood heat. Inside, Volant's 5-layer cleanable Pro 5 oiled cotton gauze filter provides high volumetric airflow and fine particulate filtration with washable, lifetime reusability. The smooth intake tube incorporates precision factory sensor ports to ensure accurate Mass Air Flow (MAF) and temperature sensor readings without triggering check engine lights on stock ECU calibrations.

Key Features & Benefits

• Sealed Thermal Enclosure: Fully enclosed roto-molded XLPE airbox isolates incoming intake air from radiant engine compartment heat soak to reduce intake air temperatures (IATs).
• Pro 5 Cleanable Oiled Filter: Five progressively finer layers of cotton gauze media trap fine road particulate and dust while maintaining unrestricted volumetric airflow and lifetime reusability.
• Aerodynamic Intake Ducting: Smooth-bore cross-linked polyethylene tube eliminates factory acoustic baffles, resonators, and corrugations to reduce drag and enhance turbocharger spool sound.
• Factory Sensor Accommodation: Precision-molded mounting bosses accept factory Ram intake air temperature and pressure sensors for error-free ECM operation.
• Fast Bolt-On Installation: Installs in under 60 minutes using standard hand tools, mounting securely to factory chassis locations without cutting, drilling, or fabrication.
