Description
The K&N Performance Airbox is designed to dramatically reduce air flow restriction and improve the smoothness of airflow. Replacing the restrictive factory air filter and air box allows your engine to inhale more air than with the factory setup, leading to more usable power and acceleration throughout the engine's RPM range. The fully enclosed, injection-molded air box connects to the factory intake hose, and the removable lid provides easy access for cleaning the filter. Installation is straightforward, using commonly available tools and the existing air box space. K&N's No-Hassle Lifetime Limited Warranty backs the airbox system, ensuring it lasts for the life of your vehicle. Some K&N 57S Series Performance Airboxes are compliant with the latest TUV emissions and sound regulations. Check the K&N catalog or website for vehicle applications and TUV status.
