Vehicle Information
Arctic Cat EXT 550 Snowmobile (1992-1993)
The Arctic Cat EXT 550 is a high-performance snowmobile that defined the 1992 and 1993 model years. These models featured a 550cc engine, providing a robust riding experience for trail and off-trail enthusiasts. In 1992, the EXT 550 was offered in "EXT Special" and "EXT Mountain Cat" trims, both utilizing carburetors. The most significant evolution between these two years was the introduction of Electronic Fuel Injection (EFI) in 1993. The 1993 models, such as the "EXT EFI" and "EXT EFI Mountain Cat," benefited from this technology, enhancing starting, fuel economy, and consistent performance, especially at varying altitudes. This transition from carburetion to EFI represents a key change for the EXT 550 series. FAQ :
