Detailed Product Information

This Standard Ignition vapor canister is engineered for emission control service on 2017-2018 Chevrolet Silverado 1500 and 2017-2018 GMC Sierra 1500 long bed applications. The CP3665 uses charcoal media to capture fuel vapors and help keep evaporative emissions contained within the vehicle’s EVAP system. Standard Ignition manufactures this part with controlled quality processes and materials selected for consistent fit and performance.

This part cross-references 2-70525 and FVCC20193 for the same application. If you are replacing a worn or saturated canister on a Chevrolet Silverado 1500 or GMC Sierra 1500, CP3665 provides a direct replacement path for the original evaporative emissions component.

Common Repair Symptoms
