1999-2004 Mustang GT: Performance Parts, Accessories, Specs & More

Sharp lines. Distinguished contours. A forward-thinking design that's still relevant decades later. Yes, we're talking about the New Edge Mustang, a Ford classic that's garnered tons of fans since its design was introduced with the 1999 Mustang GT.

Don't be mistaken — this beast is more than just a pretty face. While the "New Edge" might not be all that "new" anymore, there are plenty of reasons why the 1999 to 2004 Mustang GT models have stood the test of time. Lethal Performance is here to round up the specs on this wild stallion and help you narrow down some of the best 1999-2004 Mustang GT performance parts & accessories to get it galloping.

What Is A New Edge Mustang?

The fourth generation of Mustangs, known as the SN95 era, started in 1994. It continued until the 2004 model year, but in 1999, it was time for a design refresh. The 1999 Mustang GT didn't completely deviate from the look of the previous SN95s — it just looked sharper. The contours, creases and body lines were edgy, a result of Ford's line-wide "New Edge" stylings. Thus, the New Edge Mustang was born, a perfect pony for the late 90s and early 2000s. The following GTs fall under the New Edge banner:

  • 1999 Mustang GT
  • 2000 Mustang GT
  • 2001 Mustang GT
  • 2002 Mustang GT
  • 2003 Mustang GT
  • 2004 Mustang GT

While the New Edge updates were largely cosmetic, some new features were added, and the GT got some power upgrades, including a higher horsepower engine. The New Edge Mustang was a perfect evolution — and end — for the SN95 era, with the 2004 Mustang GT closing it out in style.

What Engine Is in the 1999-2004 Mustang GT?

Every 1999-2004 Mustang GT utilizes the Ford 4.6 Modular V8, an engine that was somewhat controversial upon its inclusion with the first SN95s, mostly because it wasn't a 5.0L V8. However, the New Edge Mustang is actually where a lot of gearheads started to come around on this platform. Better flowing heads gave the engine's horsepower output a swift kick in the ass, making the 1999 Mustang GT a force to be reckoned with — a trend that its New Edge brethren would continue.

This engine is also known for being incredibly durable and easy to mod — two major reasons why the New Edge Mustang is still popular. It's not uncommon to see a 1999-2004 Mustang GT tearing up the track today, though it's likely been modded into beautiful oblivion.
