Genuine BMW 16-13-7-303-943 Vapor Canister Evaporative Emissions Charcoal Canister

The Genuine BMW Vapor Canister (part number 16-13-7-303-943) is a critical evaporative emissions control component designed specifically for 2014-2021 BMW i3 and i3s models equipped with the range extender. Also known as the charcoal canister or EVAP canister, this OEM emission control device captures and stores fuel vapors from the fuel tank, preventing harmful hydrocarbons from escaping into the atmosphere.

Key Features:

• Genuine BMW OEM part engineered specifically for i3 range extender models
• Activated charcoal construction absorbs and stores fuel vapor until engine operation
• Prevents evaporative emissions from entering the atmosphere
• Works with purge valve system to route stored vapors to engine for combustion
• Essential for passing emissions testing and maintaining check engine light compliance
• Direct replacement for damaged or saturated canisters

This vapor canister is part of the vehicle's EVAP system and plays a vital role in reducing volatile organic compounds (VOC) emissions. When the engine is off, fuel vapors pass through a vent line into the canister where they are absorbed by activated charcoal. During engine operation, these vapors are purged and routed to the engine via an electronic solenoid, where they are burned as part of the normal combustion process. A malfunctioning canister can trigger check engine lights with EVAP-related trouble codes and may cause gasoline odors or prevent the vehicle from passing emissions inspections.
