The Volant Pro5 closed-box air intake for 2011–2018 Toyota FJ Cruiser and 2011–2020 4Runner 4.0L V6 is a bolt-on cold air system that pairs a closed filter box with a high-flow Pro5 washable, oiled cotton-gauze filter. Designed to increase airflow versus stock, the filter is pre-oiled and serviceable with long maintenance intervals and the system shields intake air from engine heat for more consistent performance.
