The K&N High-Flow Replacement Air Filter is a simple, reusable upgrade for Ford F-150 Raptor owners who want improved airflow without replacing the factory intake system. Its layered, oiled cotton-gauze media is engineered to reduce airflow restriction while capturing contaminants before they reach the engine. The filter installs directly into the original airbox with no tuning or permanent modifications required.

Unlike disposable paper filters, the K&N 33-2385 can be cleaned, re-oiled and reused throughout the life of the truck. This makes it a practical upgrade for daily-driven Raptors as well as trucks that regularly see towing, trail use or dusty environments. The filter arrives pre-oiled and ready to install.
