Features: Protects critical components, forms a protective layer, extends component lifespan, and helps maintain the effectiveness of the sound barrier under the hood for a long time; Material: The car engine soundproof cover is made of sound-insulating material, with heat insulation and soundproofing functions, reducing external noise and creating a comfortable driving environment; Installation: Quick installation without complicated tools, and provides lasting improvement in comfort and performance; Core Functions: Significantly reduces engine compartment noise and enhances ride comfort. Through a multi-layered composite structure including high-density sound insulation cotton and damping layers, it absorbs and blocks combustion noise, valve and gear mechanical noise generated during engine operation, resulting in a substantial reduction in noise transmitted to the cabin. Auxiliary Heat Dissipation Design: Some new soundproof covers integrate a water-cooled circulation layer or heat sink structure, actively dissipating heat while providing sound insulation, addressing the weakness of traditional soundproof covers that only "insulate but don't dissipate" heat., Manufacturer: CEWSUIO
