2003 Mustang Parts

The 2003 Mustang saw two exciting trim variants. The first was the SVT Cobra. This trim featured torque and horsepower upgrades, independent rear suspension, special alloy wheels, and the Tremec 6-speed transmission. The second trim option was the return of the Mach 1, offering improved horsepower and retro interior stylings. Whether you drive the stock model SN95 or one of the exclusive trims, we offer parts to help upgrade or rebuild your Mustang.

A fresh set of racing seats will restore comfort to your interior and, depending on the set you choose, could offer benefits like harness slots and roll cage compatibility. These features are ideal if you plan to race your Mustang or participate in any autocross events.

Suspension upgrades like performance sway bars and coilovers are a must if you want to keep your car grounded during tight turns and hard corners. A solid set of brake pads and rotors are also a good idea if you want better control over your ride.

Swapping in a crate engine and adding a supercharger or cold air intake will provide enormous gains in horsepower and torque. While these upgrades tend to be difficult and time-consuming, the increased performance is more than worth the labor.

Not your Mustang’s model year? Check out parts for these SN95 Mustangs: 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, or 2004.
