[MaximusDella]

Car noise comes from: 1. Engine carbon buildup; 2. Shock absorber failure; 3. Large gaps in the cabin or vehicle body; 4. Tire aging; 5. Internal damage to valve guides; 6. Cooling system failure; 7. Poor oil quality; 8. Engine misfire; 9. Spark plug carbon buildup. Methods to reduce car noise include: 1. Applying sound-absorbing foam material under the engine hood; 2. Installing sound-absorbing cotton material in the trunk, at the bottom of the trunk, and on the wheel arches on both sides of the trunk; 3. Installing sealing strips inside the doors; 4. Installing professional damping plates in areas prone to noise; 5. Replacing tires.
