K&N Performance Intake Kit MAZDA 6, 2.3L, 16V, L4, 164BHP

The K&N 57i Series intake kit for your 2003-2010 Mazda 6 with the 2.3L engine is designed to replace the restrictive factory air box. This kit frees up airflow, allowing your engine to breathe more easily and potentially gain power throughout the RPM range. The extra surface area of the open-air filter means it can capture more dirt, extending its service life up to 100,000 miles before needing a cleaning.

This kit includes a large, washable, and reusable K&N air filter that connects directly to the throttle body via a custom-designed tube assembly. The adapters are made from durable materials like steel, aluminum, silicon, or reinforced nylon to ensure they hold up over time. While this kit is designed for improved performance, it's important to note that it is not legal for sale or use in California and other states that adopt California emissions standards.
