Automotive Throttle Body or Intake Butterfly Valve

The item appears to be an automotive component, specifically a throttle body or an intake butterfly valve. It is constructed primarily from metal, likely aluminum, given its bright, somewhat matte silver finish. The visible portion is primarily circular, showcasing a central shaft with a flat, disc-shaped valve (the 'butterfly') attached. Two screws secure this disc to the shaft, indicating a mechanical assembly designed for precise rotation. Around the perimeter of the circular opening, there's a darker ring, which could be a seal, a gasket, or simply a discolored edge of the housing. The overall apparent condition seems new or very lightly used, as there are no visible signs of significant wear, corrosion, or damage such as scratches or dents on the metallic surfaces. The item is currently enclosed in a clear plastic bag, suggesting it might be new, a replacement part, or stored to prevent dust and damage. The craftsmanship appears to be industrial standard, with smooth metallic surfaces and securely fastened components. There are no readily discernible manufacturer marks, part numbers, or signatures in the provided image. Its size is difficult to estimate precisely without a reference, but it seems to be a common diameter for a single-bore throttle body in a passenger vehicle application. It likely belongs to a modern internal combustion engine system.
