The Link G4X WRXLink (V10) WRX107X ECU is a direct-fit engine management system designed for Subaru Impreza WRX platforms using the EJ25 engine. It installs into the factory ECU enclosure and connects directly to the OEM wiring loom with no modification required.

This ECU is intended for manual transmission vehicles only and supports factory electronic throttle while providing advanced tuning capability through the G4X platform.

Important – Pin check required: To confirm compatibility, check pins A1–A3 on the OEM connector. If pins A1–A3 are empty, use the WRX107X (this ECU). If pins A1–A3 have wires, use the WRX104X. This check is essential as some late-2006 vehicles require the WRX107X.
