The Rugged Ridge cold air intake kit for 1991–2001 Jeep Cherokee XJ with the 4.0L engine replaces the restrictive factory airbox to improve throttle response, acceleration and fuel economy while remaining 50-state legal. It uses a polished mandrel-bent aluminum intake tube, a black powder-coated heat shield and a high-flow dry conical panel filter that never needs oiling, offering up to 10 hp and improved fuel economy with a bolt-on, no-drill installation.
