Volant Performance Pro5 Closed Box Air Intake System (2011-2018 FJ Cruiser / 2011-2020 4Runner 4.0L V6) (18840) - 2011-2020 Toyota 4.0L V6
Maximize power output, improve mid-range torque, and enhance throttle response on your 4.0L V6 Toyota SUV with the Volant Performance Pro5 Closed Box Air Intake System (18840). Engineered specifically for 2011-2018 Toyota FJ Cruiser and 2011-2020 Toyota 4Runner models equipped with the 4.0L Dual VVT-i V6 engine, this high-performance cold air intake replaces the restrictive OEM air box assembly, sound-deadening resonators, and flexible rubber ducting with a high-flow, thermally insulated intake tract.
At the center of this system is Volant's heavy-duty cross-linked polyethylene closed cool air box enclosure, which shields incoming ambient air from engine bay heat soak while drawing in a larger volume of cold air through its expanded opening. An integrated high-velocity venturi filter adapter creates a seamless transition through the Mass Air Flow (MAF) sensor into the smooth-bore intake tube, smoothing air turbulence and accelerating airflow into the throttle body. Equipped with a high-flow Pro5 pre-oiled 5-layer cotton gauze air filter, this kit delivers superior filtration and street performance. Compatible with an optional Volant Throttle Body Spacer (P/N 728640) for maximum induction gains, complete with marine-grade stainless steel clamps and durable silicone couplers for a direct bolt-on installation.
