K&N 85-3549 Base Plate is a high-flow, reusable engine air filter designed to increase horsepower and acceleration while providing superior filtration. Multiple layers of cotton gauze media trap contaminants without restricting airflow.

The washable and reusable design lasts longer than disposable filters, reducing waste and long-term cost. Easy drop-in installation into the factory air box makes it one of the simplest performance upgrades available.

Proudly made for lasting reliability with a limited lifetime warranty on many models. A practical way to improve engine breathing, protect internal components, and maintain strong performance over the long term.
