Product Description

The K&N RX-2820 High-Flow Universal Air Filter is a versatile performance filter designed to fit intake systems with a **2.75" (70 mm) flange**. Whether you're upgrading a custom intake on a car, truck, motorcycle, or powersports machine, this clamp-on filter helps improve engine airflow and breathing compared to restrictive stock paper filters.

Its washable and reusable oiled cotton gauze media increases surface area for better airflow while still capturing contaminants to protect your engine. The molded rubber flange ensures a snug fit over the intake tube and absorbs vibration for a secure installation using a standard hose clamp (not included). Easy to install and service, the RX-2820 offers long-term value and performance for a wide range of aftermarket and custom intake applications.
