A motor vehicle has a hollow space between a front pillar and a fender. A noise insulator panel is mounted within and fills the hollow the hollow space between the pillar and the fender panel to block and absorb the communication of noise to the weather strip that seals the door to the pillar. The noise insulator panel includes a housing portion of compressible foam material with a base wall that is oversized to fit in compression between the pillar and the fender panel to block the communication of noise and a sidewall that extend forwardly from the base wall to define a cavity facing the engine and tires. An absorber portion fills the open cavity of the housing portion. The absorber portion is made of a fibrous material that is secured within the cavity of the housing portion and acts to absorb noise.
