Factory Subaru grounding strap. A ground strap ensures your battery will operate at a consistent and useful voltage. Broken, worn down, or improperly installed ground straps can cause your car’s engine and various electronic systems to malfunction. These problems can also be time-consuming and expensive to troubleshoot, since ground strap issues may first appear to be failures of your car’s battery or engine.
Fits all 2008-2021 Subaru WRX and WRX STI.
