Debuting in early 2002, the 2003 Cobra, code named "Terminator" by the SVT development crew, lead by John Coletti,[6] came with a supercharged 4.6 L DOHC engine. Numerous improvements were made to the power train and drive line to handle the increase from the previous model year. A cast iron block was used instead of aluminum, with stronger internals, including forged Zolner pistons and Manley H-beam connecting rods that were modified with a wrist pin oiling hole by the SVT engine builders. These upgrades were critical in order to support the 8 psi (0.55 bar) of boost delivered from the stock Eaton M112 roots supercharger. Other improvements include the use of an aluminum flywheel connected to a Tremec T-56 six-speed transmission, 3.55:1 rear axle ratio and stronger 31 spline half shafts with revised upper and lower control arms. These modifications launched the Cobra from 0-60 mph in 4.5 seconds and the quarter mile in the mid to high 12's at over 110 mph.

The new Cobra also had exterior differences: It featured a new front bumper with integrated spoiler, a new rear bumper with a black insert, visually integrating the exhaust pipes, a hood with functional dual scoops, newly designed side scoops and foldback mirrors painted in the body color. The side skirts were designed specifically for the 2003-2004 Mustang Cobra body kit, featuring a smooth body line from the door to the bottom of the car. Compared to the 99-02 Cobras, which had the taillights taken from the Canadian Mustang, featuring a yellow turn signal, the 03-04 Cobra used the standard Mustang taillights which were all red, eliminating the distinctive yellow blinker. SVT also introduced new 17" rims on the 03-04 model. Finally, the 03-04 Cobra sported a new decklid spoiler with an integrated LED brake light, as opposed to the wings seen on the older Cobras and the standard Mustangs.

2003 10th anniversary edition[edit]
For 2003, SVT offered a limited-edition Tenth Anniversary Cobra to celebrate 10 years since the introduction of the first Cobra in 1993. It featured split seven spoke Dark Argent 17"x9" alloy wheels, red inserts in the door panels, red painted brake calipers, red leather inserts in the seats, and special Tenth Anniversary badging on the decklid and floormats. SVT produced 2,003 units of the Anniversary model, 1,000 convertible and 1,003 coupe models. Anniversary models were only available in Black (775 models), Torch Red (734 models), and Silver Metallic (494 models).

The 2004 Cobra was much the same as the 2003 Cobra with a few minor updates, including new paint color options (Screaming Yellow, Competition Orange and Mystichrome (see below), a slightly updated exhaust system, rumors of up to 20+ more horsepower than the 2003, as well as some minor interior changes.

2004 Mystichrome Cobra[edit]
As a special for 2004, SVT brought back the MystiChrome Cobra paint scheme from 1996. The color changes from a bright, metallic topaz which then transitions to cobalt blue, then to royal purple, and finally into a deep onyx black. This color variant was produced 1010 times, 515 as coupes and 495 as convertibles. These cars came with the chromed 17" SVT wheels as a standard. They also featured color-shifting leather inserts in the seating surfaces and in the steering wheel. The color is very expensive, thus any kind of damage is problematic, and it takes a lot of research to find the original. The color was originally designed by DuPont, but sold to BASF, who finally supplied the color to Ford. The color is called "2004 Ford Mustang Cobra Mystic Chrome Metallic" and costs about US$150/pint.[7]

A definitive history of this model and John Coletti's SVT operations was captured in the non-fiction book Iron Fist, Lead Foot by Frank Moriarty.
