The engine is the heart of your Challenger — every performance mod either helps it breathe better, burn fuel more efficiently, or force more air in. These upgrades range from simple bolt-on air intakes to complete supercharger kits. Even small changes to how air and fuel get into the engine can make a noticeable difference in how the car feels.
High-flow billet rails replace stock plastic ones; required for serious forced-induction builds and aftermarket injectors over ~80 lb/hr.
