Fantastic Engine Sound and Increased Air Flow

Your 4Runner is already a powerful vehicle, and with the K&N 57-Series OEM Air Box Intake System, you can reach even higher levels of power, acceleration, and improved engine sound. The intake system replaces your factory air filter and intake tube while utilizing the OEM air box. The 57-Series Air Box Intake System allows your SUV to breathe through a more straight and smooth pathway, which means more airflow. Increasing the airflow results in your truck having heightened power and acceleration. The air intake comes with a K&N high-flow air filter and an intake tube that connects to your 4Runner's OEM Air Box. The aerodynamically engineered intake tube directs the air into the engine's throttle body, which provides the power gain. Boost the acceleration and power of your 4Runner, while delivering a deeper engine sound, with the K&N 57-Series Air Box Intake System.

Durable Construction

The 57-Series includes an air filter that uses cotton gauze filter material and is completely washable and reusable. The intake tube is constructed from High-Density Cross-Linked Polyethylene to ensure heat dissipation and performance airflow. K&N has designed the intake system to install in 90 minutes or less using simple hand tools and includes all necessary installation instructions and hardware. To help protect your investment, K&N offers a 10-Year/Million Mile Limited Warranty.
