The stock air box on a 2.4L is a restriction that sits close to engine heat. Moving the filter away from it and straightening the path cleans up the intake side.
The Rugged Ridge kit swaps the factory air box for a polished aluminum mandrel bent intake tube. A black powder coated heat shield separates the filter from engine heat, dirt and debris, and a high-flow conical air filter does the breathing. The dry panel filter never needs oiling, so excess oil cannot foul the air flow sensor. It installs as a bolt-on.
