Fits select 2011-2020 Toyota 4Runner and 2011-2014 FJ Cruiser (4.0L) models.

The Volant Pro5 Closed Box Air Intake System is engineered to improve airflow while providing superior engine protection in both on-road and off-road environments. By replacing the restrictive factory airbox with a rugged, heat-shielding enclosure, this system keeps intake temperatures low and prevents moisture and debris from reaching the filter. The airbox features a signature smoked acrylic lid, allowing for quick visual inspection of the filter without needing to disassemble the housing.

At the core of this system is the Pro5 high-performance air filter, featuring five layers of oiled cotton gauze textile pleated between aluminum screens. This reusable filter is designed for maximum flow and 98% filtration efficiency, offering extended maintenance intervals of up to 40,000 miles depending on driving conditions. Installation is a straightforward bolt-on process that utilizes factory mounting points and typically takes less than one hour.
