K&N Engineering knnE-0785

The K&N drop-in High-Flow air filter for 2008–2010 Ford F-250 Super Duty 6.4L diesel replaces the factory element to increase airflow and support higher engine efficiency. The washable, reusable oiled cotton media is layered to trap contaminants while improving flow, and is designed for long-term service life. These drop-in filters install easily into the factory airbox and are backed by K&N’s No-Hassle Lifetime Limited Warranty. Reusable design also helps reduce disposable filter waste.
