The SPT High Flow Air Intake is constructed of 319 diecast aluminum, manufactured to ensure the smoothest high flowing bends. Each system includes a silicone-reinforced boot, anti-vibration mounting system, stainless steel t-bolt clamps, and a SPT 4-layer cotton gauze filter with a built in velocity stack for smooth air flow. The intake is coated in new gunmetal gray-textured powder-coat finish. Professionally dyno tested and when combined with the SPT Heat Shield and SPT Performance Exhaust System, produces up to 30hp and 20 lb-ft of torque on a stock 2007 STI, up to 10hp and 17 lb-ft of torque on a stock 2007 WRX, and up to 30hp and 30lb-ft of torque on a stock 2007 Legacy GT Sedan when measured at the wheel. Installation of High Flow Air Intake System will result in increased turbocharger and diverter valve air flow sounds during operations. This condition is indicative of normal operation.
Fits: 2003-2007 Impreza WRX/STi
