This is an authentic, original factory equipment (OEM) rear engine lid ventilation cover grille manufactured by Ferrari for the legendary Testarossa supercar model years spanning 1984 to 1991. Bearing the official factory manufacturer part number 61500500, this specific panel is colloquially known as the rear grille for the air exhaust. Finished in its correct satin black protective coating, the structural piece features a precision-spaced horizontal mesh matrix designed to optimize heat dissipation from the mid-mounted 4.9L flat-12 engine bay. The component is in pre-owned condition, safely tagged, and preserves all factory mounting locator alignment tabs along its perimeter framework.
