The aFe Takeda Stage-2 Pro 5R cold air intake for 2015–2017 Subaru WRX STI (2.5L) replaces the factory intake to increase flow and produce measurable gains. Takeda reports up to 9 horsepower and 9 lb-ft of torque improvement while outflowing the factory intake by about 24%. A one-piece powder-coated heat shield protects the filter and the kit includes mandrel-bent tubing, hardware and a Pro 5R filter for high-flow filtration.
