Keep fuel vapors contained instead of venting to the atmosphere with the Standard Ignition Vapor Canister CP3594. It's a direct-fit replacement for the 2010 Buick Allure, 2012-2016 Buick LaCrosse, 2014-2015 Buick Regal, 2013-2019 Cadillac XTS, and 2019-2020 Chevrolet Impala.
As the storage heart of the evaporative emissions (EVAP) system, the canister holds activated charcoal that adsorbs fuel vapors from the fuel tank so they aren't released into the air. During the purge cycle, the stored vapors are drawn into the engine's intake to be burned during normal combustion.
- EVAP vapor storage: traps fuel tank vapors in its charcoal media until the system is ready to purge them.
- Emissions control: routes captured vapors to the intake for combustion, helping the EVAP system operate as intended.
- Direct-fit design: installs on the listed applications as a replacement for a worn or saturated original canister.
If a saturated, cracked, or failed canister is the cause of an EVAP fault, fuel odor, or a related check-engine code, this replaces it — diagnose the system first, since those symptoms can have other causes.
