This BMW Right Quarter Panel Insulator matches the factory application used on BMW 328i/335i/335is/M3 from 2007–2013. It installs on the right side behind the body trim to reduce noise and isolate the adjacent cavity.
BMW’s original replacement-parts program is built around model-specific geometry and the equipment installed at the factory.
