K&N Performance Intake Kit for Select 2001-2004 Ford and Mazda (V6-4.0L) 57-2529-1

Fits select 2001-2004 Ford Explorer, Explorer Sport, Explorer Sport Trac, Ranger, and Mazda B4000 (V6-4.0L).

The K&N 57-2529-1 Performance Intake Kit is designed to replace the restrictive factory air box and intake tubing on your Ford or Mazda, providing a smoother, higher-volume path for airflow. By using a rotationally-molded high-density polyethylene (HDPE) tube, this system reduces air turbulence and helps maintain lower intake temperatures. The oversized conical air filter is constructed with K&N’s signature oiled cotton media, offering excellent filtration and a service interval of up to 100,000 miles under typical highway conditions.

This kit includes a vehicle-specific heat shield to help isolate the air filter from engine bay heat, ensuring your engine breathes cooler, denser air. This complete bolt-on system is designed for a straightforward installation that can typically be completed in under 90 minutes using standard tools.
