K&N XStream Universal Clamp-On Air Filter - 2.438in ID x 4.5in Base x 6.563in H - RX-3800

The K&N XStream Universal Air Filter (RX-3800) is engineered to maximize surface area and airflow in high-performance and racing environments. By incorporating a pleated filter directly into the top of the assembly, the XStream design provides significantly more filtration media than a standard solid-top filter, extending service intervals and reducing air restriction.

Built for demanding use, this filter features ultra-strong molded pliable rubber flanges designed to absorb engine vibration for a secure, leak-free seal. The flexible flange material allows for up to 1/16 inch (1.5mm) of stretch to accommodate slight variations in intake tube sizing. Like all K&N performance filters, the XStream media is fully washable and reusable, offering a long-term solution for custom intake systems.
