Mustang 1999-2004 GT
Our most popular kit, the 99-04 Mustang GT kit , has taken the aftermarket by storm. Want 430 reliable rear wheel horse power from you street car? Then simply install one of our kits on your 99-04 Mustang GT and reap the benefits of power and reliability. Drive your car daily?
No problem, this kit, on a stock '99 GT, averaged 26mpg when we drove it from Albuquerque, New Mexico to St. Louis, MO. in 2005. The car also never ran hot, and we had the A/C blasting the whole way. This is the best performance option for your 99-04 Mustang GT.
