Description

This component is intended for the Impreza 4-door (GD) model, aiming to enhance the overall driving experience by improving throttle response and the feel of gear shifts. While this mount reduces vibrations from the power unit, it's important to note that installing it may increase vibration and noise within the car body. The product information provided is based on Japanese specifications. Compatibility should always be confirmed with a local SUBARU dealership or an authorized distributor, as part numbers can differ by country.
