• contributes to the aerodynamic consistency of the lower body.

Thanks to its dedicated placement on the vehicle's left side, installation is straightforward, utilizing the factory mounting points provided by the manufacturer.

Benefits of Using an Original Floor Panel

Choosing a part that matches the factory specifications is important for both the durability and the user experience of the car. An original floor panel ensures proper alignment with other shields and body components, resulting in stable mounting and reduced unwanted vibrations or noises during driving.

Key advantages of using this shield include:

• dedicated geometry tailored to the W164's construction,
• the ability to maintain the original underbody lines,
• easier inspection of the floor's technical condition due to an organized shield layout,
• compatibility with Mercedes' factory mounting solutions.

Item Condition and Service Application

This underbody shield is from secondary circulation, making it an attractive service solution for users seeking factory-specification parts at a reasonable budget. This type of component is particularly useful for:

• post-accident repairs in the floor and sill areas,
• replacing missing shields after previous bodywork repairs,
• restoring the completeness of the underbody assembly in vehicles operated in more demanding conditions.

Using an original shield helps maintain the underbody's structural integrity, which is important for protecting mechanical components and for the vehicle's future resale value.
