This product will be back in stock mid year 2022 due to supply chain issues. We apologize for the inconvenience.

Is your stock harness damaged? Is the harness you picked up for the project falling apart with broken connectors? Are you having electrical issues with a harness you're just not sure about? Are you missing this harness completely after importing your engine? iWire has you covered. 

With all new materials, high quality sleeving, and designed with top notch fit and finish in mind, our 2.0 WRX and STi Engine Wiring Harness is more than just a stock replacement.
