The Rugged Ridge cold air intake kit for 4.0L 1991–1995 Jeep Wrangler YJ replaces the restrictive factory air box with a polished mandrel-bent aluminum tube and a black powder-coated heat shield to draw cooler air through a high-flow conical dry panel filter. The dry design never needs oiling, helping protect the airflow sensor. Bolt-on installation is simple, it can improve throttle response and acceleration, and may boost fuel economy up to 10%.
