Keystone MB1228156 Engine Splash Shield Under Cover Center

The Keystone MB1228156 is an OEM-replacement center engine splash shield, also commonly referred to as an underbody shield, engine skid plate, or engine under cover. Designed as a direct-fit replacement for the Mercedes-Benz S-Class (221 Chassis), this part restores the factory underbody protection that keeps the engine bay safe from the elements.

The engine splash shield serves as a protective barrier positioned beneath the engine compartment. It shields the engine and critical underhood components — including belts, pulleys, and electrical systems — from road debris, dirt, moisture, and other hazards encountered during normal driving. It also contributes to underbody aerodynamics by smoothing airflow beneath the vehicle.
