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.
Tuners & Programmers
A tuner or programmer plugs into your car's diagnostic port and changes how the engine computer (ECU) operates. It can adjust fuel delivery, spark timing, transmission shift points, and more. Think of it as unlocking potential that's already in the engine but held back by conservative factory programming. Almost every build benefits from a tune once you start adding mods.
