The 2004 FIA GT Imola 500 km was the eighth round the 2004 FIA GT Championship season. It took place at the Autodromo Enzo e Dino Ferrari, Italy, on September 5, 2004. This race featured the competition debut of the Maserati MC12, with AF Corse entering two cars. The FIA had initially refused homologation of the road versions of the MC12 due to the car being wider than the current regulations allow. However, with agreement from other FIA GT teams, the MC12 was allowed to participate in the GT1 class with revised bodywork, a narrower rear wing, and no ability to score championship points.
