Most people install lower engine guards based on the following benefits:

1. Under extremely bad roads, prevent particularly severe stone hits that can damage the chassis' heavy maintenance parts, such as breakdown of the engine oil pan or gearbox housing.

2. For vehicles with a low chassis, the addition of a lower engine guard can prevent damage to the chassis parts caused by the bottom support.

3. In fact, the most important role is that our own subjective feelings are good!

In fact, there are many important parts in the engine compartment that affect driving performance. Installing a lower engine guard is like installing a partition for the heart, which will bring the following complications:

1. It may change the air flow in the engine compartment when traveling, which will have a greater impact on the heat dissipation performance of the engine compartment, and will cause damage to the engine over time.

2. The installation of the lower guard plate will change the vibration performance of the engine, which will cause the idling vibration to deteriorate, the acceleration vibration to deteriorate and the acceleration roar. If the installation is not good, it may form a resonance cavity with the engine compartment, making the engine noise louder.

3. The lower guard plate is installed to protect the engine from being bumped, and it will also become a place to hide dirt. Stones, dust, and dirt tend to deposit on the guard plate, especially the larger stones are easy to get stuck between the guard plate and the parts in the cabin, which may cause abnormal engine noise and even damage the engine. If you install a lower guard, be sure to clean it regularly.

4. The lower guard plate of the engine itself is a plate with less rigidity, which may affect the collision performance of the vehicle (this point is not yet conclusive).
