This is the stock injector resistor pack that is on all twin turbo 3000GT and Stealth models, mounted to the firewall on the passenger side. These can go bad over time and need replacing. But they are NOT available new from Mitsubishi any more. They can also be used for twin turbo conversions when you are going to run low-impedence injectors.
NOTE: Used parts are SOLD AS IS and carry no warranty and are non-returnable. By purchasing this used part, you agree to these terms.
