Volant Closed Box Cold Air Intake with DryTech Dry Filter (01-06 6.0L Sierra 2500 HD)Find parts that fit my vehicle

High‑Capacity Enclosed Air Box Design. The Volant Closed Box Cold Air Intake replaces the restrictive factory intake system with a large, sealed air box and custom-engineered ducting. This design draws cooler ambient air from outside the engine bay, helping reduce intake temperatures and improve combustion efficiency. The larger air-inlet opening and optimized duct geometry increase airflow volume and velocity, supporting better engine breathing and performance under load or acceleration.

DryTech Dry Filter for Easy Maintenance. This version of the Volant Closed Box Cold Air Intake includes Volant’s DryTech dry-filter media, which offers a reusable, low-maintenance alternative to traditional oiled filters. The DryTech filter can be cleaned with soap and water, dried, and reinstalled, eliminating the need for oiling and reducing long-term maintenance costs. It’s ideal for users who want a straightforward cleaning process and prefer dry filtration for its simplicity and reliability.

Better Airflow and Throttle Response. By eliminating the factory resonator box and restrictive tubing, the Volant intake introduces a smooth venturi-style adapter and high-capacity enclosure that enhance airflow dynamics. This Volant Closed Box Cold Air Intake allows your engine to breathe more freely, resulting in sharper throttle response, improved engine sound, and, under certain conditions, modest gains in horsepower and fuel efficiency. It’s a performance-focused enhancement that supports both daily driving and towing applications.

Maintenance Advantage and Filter Flexibility. The Volant Closed Box Cold Air Intake’s washable and reusable design reduces the need for frequent replacements, offering a cost-effective and eco-friendly solution. The enclosed air box also helps shield the filter from hot engine air, especially during idle or low-speed driving, preserving intake efficiency.
