Keystone AU1228118 Engine Splash Shield Rear Under Cover Audi A6 Quattro S6 Wagon

The Keystone AU1228118 is a rear engine splash shield (under cover) designed as a direct OEM-style replacement for the Audi A6 Quattro and S6 Wagon equipped with an automatic transmission. This part replaces OEM part number 4B0863822L and is engineered to restore factory-level underbody protection.

The engine splash shield mounts to the underside of the vehicle and acts as a barrier between the road and critical engine and drivetrain components. It helps deflect water, mud, road debris, and gravel that would otherwise be thrown upward into the engine bay, protecting hoses, wiring, and other sensitive components from premature wear, moisture intrusion, and corrosion.
