LOCATE THE VEHICLE EMISSIONS CONTROL INFORMATION LABEL
To determine which catalytic converter check your Vehicle Emission Control Information on your vehicle, it is necessary to determine the specific emissions system installed by the OE manufacturer. Or make an appointment for FMS Performance.
This information is provided on the vehicle’s Emissions Control Information Label.
This label is located in the engine compartment in a visible location – usually on the hoot underside, strut tower, radiator support, fan shroud or firewall.
DETERMINE THE EMISSIONS CERTIFICATION
A vehicle is a California Emissions Certified model if the Vehicle Emissions Control Information label references: “California,” ”50-State,” “CARB,” or “ARB.” This is vital information if regulations in your state mandate replacement converters be CARB-compliant.
LOCATE THE ENGINE FAMILY NUMBER
The EFN, also referred to as the Engine Family Number, Engine Family Code, or Test Group Number, is prominently located on the Vehicle Emission Control Information label, along with other important emissions specifications. This information is vital when looking up parts in the application catalog, to ensure proper fit and in navigating state-mandated aftermarket replacement converter regulations. All OBD applications for California can be found here. Be sure to verify your EFN to avoid misapplication of the replacement catalytic converter. If the label is missing, it is necessary to contact the OE dealer for the information, or to order a new Emission Control Information Label.
Determining the proper replacement converter for a particular vehicle takes a little research. FMS Performance will specifically indicate which converters are legal for use in California and on which vehicle models they can be installed.
