The Volant Pro5 closed-box air intake for 1999–2002 Toyota 4Runner with the 3.4L V6 replaces the stock intake to increase airflow and protect the filter, improving throttle response and drivability. The kit includes a closed filter box, air duct, connectors and clamps plus a Pro5 5-layer oiled cotton gauze filter that ships pre-oiled. Rugged construction and a bolt-on install in under an hour let it outflow factory intakes and extend maintenance intervals.
