Product Description

The K&N E-0634 is a direct drop-in high-flow replacement air filter designed for the 2021-2026 Ford Bronco equipped with the 2.3L EcoBoost I4 or 2.7L EcoBoost V6 engine across all trim levels from Base through Everglades and Stroppe Edition, in both 2-Door and 4-Door configurations. As a direct replacement for Ford OEM filter FA2022, the E-0634 installs directly into the factory airbox with no modifications required, delivering the high-flow cotton gauze filtration K&N is known for in a simple, tool-free upgrade. The multi-layer oiled cotton media provides greater airflow than the restrictive factory paper element while maintaining the engine protection needed for both street and off-road use.

The E-0634 is an especially practical upgrade for Bronco owners who use their trucks off-road, as the washable and reusable design means a clean filter is always ready to swap in while the other dries after cleaning. Service is required only every 75,000 miles under normal highway conditions, though trail-intensive driving may warrant more frequent inspection. Backed by K&N's 10-Year/Million Mile Limited Warranty, the E-0634 pays for itself over multiple OEM paper filter replacement cycles and is the most straightforward performance and longevity upgrade available for the 6th-generation Bronco's EcoBoost intake system.
