Show original supplier description
The K&N 57i Performance Air Intake Kit is engineered to replace your vehicle's restrictive factory air box, offering a significant increase in airflow and engine performance. By incorporating K&N's High-Flow air filter technology and a larger filter size, this system allows more cold air into the engine, resulting in noticeable horsepower and acceleration gains across the entire RPM range. Designed specifically for your vehicle's characteristics and available underhood space, the 57i kit ensures optimal performance. The larger K&N air filter captures more dirt than stock filters, extending the interval before cleaning is needed up to 100,000 miles, contributing to better engine performance and longevity. The filter is washable and reusable for the life of your vehicle. Installation is straightforward, typically completed in under 90 minutes without requiring drilling or modifications, utilizing factory mounting locations. This K&N air intake system is compatible with your OEM computer system and is backed by a 10-Year/Million-Mile Warranty.
