Motorad 31342749 EVAP Vapor Canister Charcoal Canister

The Motorad 31342749 is a replacement evaporative emissions (EVAP) vapor canister, also commonly known as a charcoal canister or carbon canister. It is a direct-fit replacement engineered to OEM specifications for compatible Volvo vehicles and is designed to restore proper function to the vehicle's evaporative emission control system.

The vapor canister is a critical component in the EVAP system. Packed with an activated charcoal bed, it captures and stores fuel vapors vented from the fuel tank, preventing them from escaping into the atmosphere. When the engine is running, those stored vapors are purged back into the intake manifold to be burned, reducing harmful emissions and contributing to improved fuel efficiency.

Key Features:

• Direct-fit replacement for OEM vapor canister / charcoal canister
• Activated charcoal bed matched to OEM capacity and adsorption grade
• Multi-layer internal flow design for stable, consistent adsorption efficiency
• Engineered to address known OE failure modes including housing crack points and port geometry
• Includes carbon filter with fittings for complete installation
• Helps vehicle meet evaporative emissions standards
• OEM Part Number: 31342749 | Supersedes: 30684418, 8634819

A faulty vapor canister typically triggers a check engine light and can cause the vehicle to operate inefficiently while increasing tailpipe and evaporative emissions. Replacing it with a quality unit restores EVAP system integrity and helps the vehicle pass emissions inspections.
