WRX / STI 75 MM Throttle Body Upgrade

Engineered to retain the stock idle control and TPS, this high-performance throttle body is designed for 2004 and earlier WRX and STI models equipped with Drive-by-Cable systems. CNC-machined from billet aluminum, the 75 mm diameter delivers nearly a 56% increase in throttle cross-sectional area compared to stock, resulting in improved horsepower and significantly enhanced throttle response—even when used with stock intake pipes and turbo. The complete kit includes a stock manifold adapter plate, a 60 mm hose adapter for immediate compatibility with OEM intake piping, a 75 mm hose adapter for larger setups, and all necessary mounting hardware. When paired with upgraded 75 mm intake piping, it opens the door to virtually unlimited performance potential, all while meeting the brand’s renowned quality standards and warranty coverage.
