Fun Facts
1. The Fox body platform gets its name from the Ford Fox platform, which also underpinned mundane family cars like the Fairmont. 2. The 1989 model year marked the final year for the speed-density engine management system before switching to mass air flow in 1989.5/1990. 3. It became the undisputed king of cheap street racing in the 1990s and 2000s due to the massive aftermarket support for the 5.0 engine.
