Used 2006 Subaru Impreza WRX STI Pricing

For 2006, the Subaru Impreza benefits from a styling refresh, new trim levels and minor mechanical updates. On the outside, there's a new three-section grille and swoopier headlights, subtly restyled fenders for the sedan and new taillight clusters. New trims include a less expensive WRX TR sedan and an upscale WRX Limited sedan and wagon. The 2.5 RS trim level becomes the 2.5 i. Mechanically, the WRX's engine goes from 2.0 liters to 2.5 liters of displacement and now makes 230 hp and 235 lb-ft of torque. Other Imprezas get a horsepower boost from last year's 165 hp to 173. The WRX line also gets aluminum front suspension links, standard 17-inch wheels, upgraded brakes with red four-piston calipers up front, and a quicker steering ratio.
