Andrew Cilio The Mustang underwent minor changes for 2004. 2004 was the Mustang's 40th anniversary, and as such, all models received a "40th Anniversary" badge on the fenders. The base model received a new 3.9L V6 midway through the year which offered no increase in power, weight, or fuel economy. Two new colors, Competition Orange and Screaming Yellow, were added to the Mustang lineup.
The GT went unchanged for 2004, but a new package called the 40th Anniversary Edition was offered on the base and GT models. A new color, Crimson Red, was offered only on the 40th Anniversary Edition. The only other colors offered were Black and Oxford White. 40th Anniversary Edition models also came with premium wheels, body-color fold in mirrors, "40th Anniversary" floormats, and beige stripes on the trunk, hood, and sides. They also came with an interior upgrade package which included larger headrests and silver-colored interior trim. Only 5700 of the 40th Anniversary Edition Mustangs were made.
The 2004 Mach 1 returns still powered by a 4.6-liter 32-valve dual-overhead-cam V8 generating 320-horses. This ram-air engine features the attractive “shaker system” with a modified upper intake, calibrated cams, forged crank (cast crank for auto), and performance exhaust manifolds.
The Cobra also comes back with a standard M112 roots style Eaton supercharged V8 under the hood, packin’ 390-RWHP. Also known as “Terminator”, the Cobra has a cast iron block instead of aluminum, stronger internals like forged Zolner pistons and Manley H-beam connecting rods modified with a wrist pin oiling hole built by the SVT building team. The Tremec T-56 six-speed transmission, 3:55:1 rear axle ratio, aluminum flywheel and revised upper lower and control arms. A new color was added to the Cobra's options list called MystiChrome. This color-changing paint was similar to the Mystic paint offered on Cobras in 1996. MysticChrome offered even better color distinction than the original, and shifted from green to blue to purple to black. The MystiChrome Cobras also featured color-changing leather seats and steering wheels. Only 1010 MysticChrome Cobras were ever produced, and the color was a $3650 option.
