Volant Closed Box Air Intake 11-20 Toyota 4Runner, 11-17 FJ Cruiser 4.0L V6

The Volant Closed Box Air Intake for the 2011–2020 Toyota 4Runner and 2011–2014 FJ Cruiser with the 4.0L V6 engine is engineered to improve engine performance by increasing airflow and enhancing filtration efficiency. This system features a large closed polyethylene intake box that draws in a higher volume of cooler ambient air compared to the factory setup. It uses a high-flow, reusable Pro 5 cotton gauze filter that requires periodic re-oiling and cleaning, ensuring excellent filtration and long filter life. The intake includes a high-velocity venturi filter adapter that provides smooth airflow through the MAF sensor, improving throttle response. Durable high-temperature silicone connectors and stainless steel clamps ensure secure, leak-free connections. Designed for easy maintenance with an insulated lid for quick filter access, this intake system is a direct bolt-on replacement but is not CARB-legal for California. Overall, it offers a durable, efficient upgrade that enhances power and engine sound without compromising protection.
