The Link G4X PlugIn ECU transforms your WRX into a precision-tuned performance machine. Enjoy the latest in engine management technology, fitted directly into your OEM enclosure with no loom modifications required.
Link Engine Management products are not recommended where installation and tuning of such products contravenes your countries laws or interferes with the vehicle safety or pollution protection features.
Choose the Right Model – Pin Check Required!
The fastest and most reliable way to determine which ECU you need is to check pins A1–A3 on the OEM connector:
- If pins A1–A3 have wires → You need the WRX104X.
- If pins A1–A3 are empty → You need the WRX107X (this listing, 225-4000)
Some late 2006 cars require the WRX107X, so this check is essential.
Vehicle Compatibility
- Designed for WRX V10 EJ25 (2.5L) 2004–2007
- Manual transmission only
- Suits GD/GG chassis with electronic throttle
- Not suitable for GR/GH/GE/GV hatchback or 3rd generation WRX
