Genuine OEM Mini Activated Charcoal Filter, part number 16136801156. This filter is a key component of the vehicle's evaporative emission control system, designed to absorb volatile organic compounds (VOCs) and fuel vapors released from the fuel tank. By trapping these vapors, it prevents them from escaping into the atmosphere, thus reducing harmful emissions. The filter is typically located in the fuel vapor line between the fuel tank and the engine's intake system. Genuine OEM activated charcoal filters are manufactured with high-quality adsorbent materials to ensure effective vapor capture and compliance with emission standards.
