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.
Cooling & Thermostat
Your engine produces enormous heat, and performance mods make it produce even more. The cooling system (radiator, thermostat, water pump) needs to keep up. A lower-temp thermostat lets coolant flow sooner, and an upgraded radiator can reject more heat. Overheating kills engines — cooling upgrades are insurance for your investment.
