Detailed Description

This vapor canister stores fuel vapors from the evaporative emission system and helps route them through the proper purge path instead of releasing them to the atmosphere. Standard Ignition CP3217 is built for Subaru evaporative system applications and matches the listed port count, hose connector layout, and canister length for a direct replacement. It is a practical choice for Subaru Forester, Subaru Impreza, and Subaru Legacy service where the original canister has cracked, saturated, or no longer seals correctly. This part cross-references 42036AC020 and CP1357 for the same application.
