K&N 57 Series Performance Intake Kit for 1991-1995 Jeep Wrangler (L6-4.0L) 57-1521

Fits 1991-1995 Jeep Wrangler Base, Islander, Renegade, Sahara, and SE models (L6-4.0L).

The K&N 57 Series FIPK system is designed to replace the restrictive factory air filter and intake housing to significantly improve airflow. This kit features a rotationally-molded high-density polyethylene (HDPE) intake tube that smooths and increases the volume of air reaching your engine, providing a guaranteed increase in horsepower and torque. By reducing air path turbulence, the system enhances throttle response and delivers a more aggressive engine note under acceleration.

Equipped with an oversized, conical High-Flow Air Filter, the system uses oiled cotton media to provide excellent filtration and airflow. The filter is washable and reusable, capable of lasting up to 100,000 miles between services under normal highway driving conditions. A custom-fit heat shield is included to protect the intake air from high engine bay temperatures, ensuring a cooler, denser oxygen charge. This entire system is designed for a straightforward bolt-on installation that can typically be completed in less than 90 minutes using standard hand tools.
