Collection: 04 STI
The 2004 Subaru WRX STI holds a special place in automotive history as the model that introduced the rally-bred STI badge to North America. Instantly recognizable with its massive rear wing, functional hood scoop, and aggressive styling, the 2004 STI took the performance world by storm. Equipped with a potent 2.5L turbocharged boxer engine producing 300 horsepower, along with Subaru's iconic symmetrical all-wheel drive and driver-controlled center differential (DCCD), the 2004 STI offered unprecedented power, grip, and control for enthusiasts and rally fans alike.
What makes the 2004 STI truly unique among its peers is that it was the first of its kind available in the U.S., representing the unfiltered essence of Subaru's motorsport heritage. With its hydraulic steering and limited electronic intervention, the 2004 model provides a raw and mechanical driving experience, offering a visceral connection to the road that subsequent models would gradually soften in favor of modern refinements. The rally DNA of the 2004 STI shines through in every drive, making it a coveted collector’s item and a legendary performance car that set the standard for future generations of STI. For many, the 2004 STI is the definitive version of Subaru’s performance icon.
