Capture and store fuel vapors before they escape to the atmosphere with the Standard Ignition Vapor Canister CP3572. It drops in as a direct-fit replacement for the 2006-2009 Pontiac Solstice and the 2007-2010 Saturn Sky, restoring the evaporative emissions (EVAP) storage function these vehicles rely on.
A vapor canister is the charcoal storage element of the EVAP system: it traps fuel vapor drawn from the fuel tank and holds it until the engine is ready to draw those vapors into the intake to be burned during a purge cycle. Replacing a saturated or cracked canister helps keep the EVAP system sealing and venting the way it was designed to.
- Purpose: stores fuel-tank vapor and routes it into the EVAP purge path instead of venting it to the air.
- Direct fit: installs on the listed Solstice and Sky applications.
- Serviceable replacement: a fresh canister for one that is cracked, saturated, or restricted.
Signs this part may need replacing: a persistent fuel odor, an EVAP-related check engine light, or a failed emissions test. If a failed vapor canister is the cause, this replaces it — diagnose the EVAP system first, since these symptoms can have other causes.
