The K&N R-1100 Universal Air Filter is engineered for high performance across a wide range of applications, from vintage ATVs to custom intake setups. Constructed with ultra-strong, molded pliable rubber flanges, this filter is designed to absorb engine vibration while ensuring a secure attachment. The high-quality rubber flange can be stretched up to 1/16 of an inch (1.5mm) to accommodate in-between sizes for a precise fit.

This round tapered filter is fully washable and reusable, offering a significant upgrade over disposable paper filters. Designed to provide high airflow, this filter may require modifications to the carburetor jetting when used as a replacement for the OEM unit to ensure optimal engine performance.
