WRXLINK - WRX6X

Free yourself from the constraints of the factory ECU.

The Link G4X WRXLink (5-6) WRX6-X PlugIn fits the Subaru WRX & STI V5-6. The ECU PCB fits discretely inside the original factory enclosure. 

Installation of Link's Subaru WRX6X ECU is a breeze - no alteration of the factory wiring loom is required. A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches. 

Factory features are supported - see Features for any exceptions.

MAP Sensor not included.
