BMW Sound Insulation Set - Genuine BMW 51488103798

Product Information

A hood insulation pad is a layer of insulating material attached to the underside of a vehicle’s hood. Its primary functions are to reduce engine noise heard inside and outside the cabin, protect the hood’s paint from engine heat, and sometimes provide limited fire protection by slowing flame spread. Over time, the insulation pad can degrade due to heat, vibration, and exposure to fluids or contaminants.

• Noise increase – more engine noise or vibration heard in the cabin or outside.
• Heat damage – hood paint fading, discoloration, or warping from excess engine heat.
• Physical deterioration – sagging, tearing, missing sections, or contamination from oil/coolant leaks.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
