Construction & Design

The Volant Closed Box Air Intake is constructed with high-quality materials designed to withstand the rigors of diesel truck use. The air filter utilizes eight layers of tightly woven textiles, pleated between robust aluminum screens that provide both protection and airflow optimization. This design ensures the filter maintains its shape and filtration efficiency over extended use.
