Engine & Power
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.
Intake Manifolds
The intake manifold distributes air from the throttle body to each of the 8 cylinders. A performance manifold optimizes the runner length and plenum volume for more power at different RPM ranges. The popular Hellcat manifold swap is one of the best-kept secrets for adding top-end power to a 6.4L engine.
