Mercedes-Benz Hood Insulation / Sound Blanket, OEM part number 1666820126, is a genuine used component pulled from a donor vehicle. This factory-engineered pad dampens engine noise and helps retain heat under the hood, reducing cabin vibration and protecting the paint from thermal stress. It fits a range of GL, GLE, GLS, and ML models with various 2.1L to 5.5L engines, including diesel, gas, and hybrid powertrains. When the insulation deteriorates or is missing, you may notice increased engine bay noise and heat transfer to the hood surface.
