Toyota 4Runner Performance Air Intake - Volant - Pro5 Closed Box - `11-`20. The Volant Pro5 Closed Box intake is a direct-fit performance replacement for 2011–2020 4Runner 4.0L V6 models, designed to improve airflow while protecting the engine.

Built around Volant's MaxFlow 5 five-layer oiled cotton gauze filter, this intake outflows the stock system while offering durable, reusable filtration. The closed filter box with a smoked acrylic see-through lid helps shield the element from engine heat and road debris, keeping intake air cooler and cleaner for consistent operation. The Pro5 filter arrives pre-oiled and ready to use; Volant rates the filtration at approximately 98% efficiency with extended maintenance intervals (up to 40,000 miles depending on driving conditions). The kit includes the closed box, air duct, connectors and clamps for a straightforward bolt-on installation that can typically be completed in under an hour. Ideal for drivers who prioritize reliable on-road and light off-road performance.
