Product Description

The K&N 63-9034 AirCharger Cold Air Intake is a performance upgrade designed for Toyota 4Runner (2010-2023) and FJ Cruiser (2006-2014) 4.0 L V6 engines. By replacing the factory airbox and ducting with a smooth-flow HDPE intake tube and a large oiled cotton-gauze filter, the system allows the engine to breathe more efficiently, drawing in cooler, denser air. This results in a dyno-tested horsepower increase of approximately 12 HP, enhanced torque, sharper throttle response, and improved acceleration.

Installation is straightforward, using factory mounting points with included hardware, typically completed in 60-90 minutes. The reusable filter lowers maintenance costs and the heat shield protects intake air from engine heat. The 63-9034 is ideal for owners seeking a reliable, long-lasting performance upgrade that improves airflow and engine responsiveness without complex modifications or tuning.
