2003 Cobra Mustangs
The 2003 Cobra Mustangs started the Supercharged Mustang revolution we have with us today!
In early 02, Ford announced the all new 2003 Cobra and with the announcement came news that everyone was waiting to hear! The 2003 Cobra would be fitted with the popular Modular 4.6 engine, but it would also have a littler kicker bolted on, in the form of a SuperCharger! The combination produced 390 horsepower from the facatory, but was immediately tweaked into the mid 500 horsepower range by crafty wrenches.
