Product Description

The K&N 33-2106-1 is a washable, reusable drop-in replacement air filter covering an extensive range of Ford, Mercury, and Mazda truck-based platforms - including the Ford Explorer (2nd and 3rd gen), Explorer Sport, Explorer Sport Trac, Ford Ranger, Mercury Mountaineer, and Mazda B-Series pickups. Spanning engine options from the 2.3L L4 through the 5.0L V8, this filter drops directly into the factory airbox across all supported applications with no modifications required, and is fully compatible with OEM MAF sensors and engine management systems.

With a cleaning interval of every 75,000 miles, the K&N 33-2106-1 is a practical long-term upgrade for owners of some of Ford's most popular trucks and SUVs of the late 1990s through early 2010s. Whether used for daily driving, towing, or light off-road, this filter delivers improved airflow and throttle response compared to a stock paper filter, making it one of the most cost-effective upgrades available for the platform.
