Standard Motor Products CP3237 Vapor Canister Purge Canister EVAP Emissions Control

The Standard Motor Products CP3237 is a direct-fit replacement vapor canister (also known as an EVAP canister or charcoal canister) designed to restore proper emissions control system function. This component is a critical part of the Evaporative Emission Control (EVAP) system, capturing and storing fuel vapors from the fuel tank and preventing them from being released into the atmosphere.

Standard Motor Products is a trusted OEM-quality manufacturer with decades of experience producing ignition, emissions, and engine management components. The CP3237 is engineered to meet or exceed original equipment specifications for a precise, trouble-free fit and reliable long-term performance.

Key Features:

• Direct OEM replacement — no modifications required for installation
• Manufactured to meet or exceed original equipment specifications
• Constructed with activated charcoal media to effectively adsorb fuel vapors
• Helps vehicle pass emissions testing by maintaining a properly functioning EVAP system
• Restores proper purge flow and vapor storage capacity
• Durable housing resistant to fuel vapors and under-hood temperatures

A failing vapor canister can trigger a Check Engine light (typically EVAP-related fault codes such as P0440, P0441, P0442, or P0446), cause fuel odor, or result in a failed emissions inspection. Replacing the canister with the Standard Motor Products CP3237 restores the integrity of the EVAP system and helps ensure compliance with emissions regulations.
