1999-2004Ford continued to set the bar for performance with the 1999-2004 Mustang line up starting with a base model V6 boasting a 3.8 L OHV Essex engine featuring a split-port induction system which pumped up the car’s output to 190 horsepower. The engine's new intake manifold runner increased the engine output even further.

At the same time, performance improvements like heads, cams, and intake manifolds on the GT saw a boost in power to 260 horsepower. Performance got an even bigger boost in 2001 when Ford switched from their standard 19 lb/hr injectors to 21 lb/hr injectors bumping output another 10 horsepower.

The Cobra saw a range of enhancements that improved both performance and looks. The Cobra’s 32-valve, 4.6L V8 was now rated at 320 horsepower.

And then there was the Mach1. High performance with a retro feel could best describe the Mach1. Based on the success of Mustang’s earlier Bullitt, Ford re-introduced the Mach1 with a 4.6L DOHC 305 horsepower engine featuring new cylinder heads. Combined with a retro style interior, this Mustang model was an instant favorite.
