It is not recommended to replace the original plastic underbody guard with a steel engine guard. You can install a resin engine guard at a physical store, which provides a cushioning effect in case of an accident, preventing damage to the oil pan. Main functions of plastic underbody guards: Most vehicle models come with a plastic engine guard as standard equipment. Its primary functions are to reduce underbody turbulence during driving, resulting in lower aerodynamic drag and reduced noise; and to protect the engine from damage caused by flying gravel and debris on the road. Disadvantages of steel underbody guards: In the event of a frontal collision, the sturdy steel guard can obstruct the engine's downward displacement, potentially causing severe injuries to passengers inside the vehicle. Additionally, steel guards are less economical as they increase the weight of the front section of the car, leading to a certain degree of higher fuel consumption.
