Volant Performance Pro5 Closed Box Air Intake System (2005-2011 Toyota Tacoma 4.0L V6) (18640)
Maximize horsepower, increase mid-range torque, and enhance throttle response on your 4.0L V6 truck with the Volant Performance Pro5 Closed Box Air Intake System (18640). Engineered specifically for 2005-2011 Toyota Tacoma models equipped with the 1GR-FE 4.0L V6 engine, this high-performance cold air intake replaces the restrictive factory air box, power-robbing sound resonators, and flexible rubber ducting with a high-flow, thermally insulated intake tract.
At the core of this system is Volant's heavy-duty cross-linked polyethylene closed air box enclosure, which shields incoming air from engine bay heat soak while drawing in a larger volume of cold ambient air. An integrated high-velocity venturi filter adapter creates a seamless air transition through the Mass Air Flow (MAF) sensor into the smooth-bore intake tube, eliminating air turbulence and accelerating airflow velocity into the engine. Equipped with a high-flow Pro5 pre-oiled 5-layer cotton gauze air filter, this kit delivers superior filtration and breathability. Compatible with optional Volant Ram Air Scoops (P/N 38140 / 38640) and Throttle Body Spacer (P/N 728640) for maximum induction performance, complete with marine-grade stainless steel clamps and durable silicone couplers for a direct bolt-on installation.
