Enhance engine performance with improved airflow and throttle response.
The K&N 57i Series Cold Air Intake is engineered to optimize airflow and enhance engine performance across various RPM ranges. This system replaces the factory air intake, allowing for increased horsepower and improved throttle response. Constructed from durable black polyethylene, the intake features a high-flow red filter that is washable and reusable, providing longevity and efficiency. Designed for easy installation, this kit typically requires 90 minutes or less to set up, making it accessible for both enthusiasts and casual users. The larger filter surface area captures more dirt, extending service intervals up to 100,000 miles before cleaning is necessary.
