The two standard modifications are a cold air intake and a tune. Just these two improvements can help your engine breathe better and give you more control over your engine's performance. Adding more substantial improvements, like headers or a supercharger, can make it feel like you're driving a whole new Mustang down the road.

The turbocharged EcoBoost can also be modified for improved performance. Intercoolers are one unique way that the EcoBoost can be improved upon. Blow Off Valves are another.

The naturally aspirated V6 and Coyote V8 are equally easy to improve on. New throttle bodies, and throttle body spacers, can improve performance slightly.

S550 Mustangs are easy to modify for even greater performance than they come stock with. Adding more power to your Mustang can be a fun way to customize your performance and get a ride that's unique to you.
