15- 4 Runner 4.0L Air Intake Kit

The 15–4 Runner 4.0L Air Intake Kit by K&N Engineering is designed specifically for fourth-generation Toyota 4Runner owners looking to enhance their vehicle's throttle response and engine efficiency. This cold-air intake system is ideal for those who want to improve airflow to their 4.0-liter V6 engine, leading to better combustion efficiency and performance.

The precision-engineered tubing minimizes turbulence and pressure losses, allowing the engine to operate more efficiently.

This air intake kit is particularly beneficial for 2010–2015 4Runner owners who seek a straightforward bolt-on modification that requires no ECU tuning or extensive fabrication. With all necessary components included, installation is accessible for those with basic mechanical skills. Upgrade your 4Runner's performance with this reliable and efficient air intake solution.
