Is it necessary to install an engine underguard for a car?

[LeManuel]

It is necessary to install an engine underguard for a car, especially for vehicles that traverse various road conditions. When driving on mountain roads or during rainy weather, mud can easily adhere to the engine, leading to uneven heat dissipation. Additionally, the engine underguard serves another purpose: it prevents impacts to the engine when driving on uneven surfaces. Frequent direct contact between the vehicle chassis and the ground can negatively affect the engine's lifespan. Generally, it is recommended that car owners opt for an aluminum alloy underguard. Aluminum alloy underguards are superior as plastic ones may get damaged when dragged. Even if an aluminum alloy underguard deforms, it can often be straightened and reused, making its service life longer.
