The filter is rated at 99.96% efficiency and combines filtration with performance. Volant states that the filter can provide maintenance-free air filtration for up to 150,000 miles, reducing routine filter service needs. This system focuses on airflow, engine protection, and long-term filtration; the supplied product information does not specify construction materials, additional intake components, or installation details.
