Without engine mount, you'd most likely be complaining about the vibration coming from the engine area each time you drive. That's how the engine mount is to safe comfortable drive.

Engine mounts are basically devices that connect the various part of vehicle to its chassis or framework.
Engine mount consists of two attached metal parts with rubber in between. One side of the mount is bolted to the engine while the other is attached to the frame. The rubber in the center absorbs vibration while allowing a small amount of movement

The engine mount keeps the engine secured , prevent it from vibrating excessively and ensures that it stays properly connected.
It also dampen vibration and noise so it will not be felt by the driver and passenger as it keeps vibration from
travelling through the frame and other parts of vehicles.
