2004-2021 Subaru STI
While the Subaru STI 6-speed transmission is widely respected for its strength, one of its weak links is the factory shift finger. A failure of this small component can cause major issues. The IAG Shift Finger is designed as a robust solution, made from high-grade materials to ensure long-term reliability and performance.
