The Vehicle Emission Control Information (VECI) label is extremely important when replacing the catalytic converter, completing emission inspections or when ordering emissions control parts.
It is necessary to determine the specific emissions system installed by the OE manufacturer when replacing a converter. That information can be found on the VECI label.
The VECI label is typically located on the underside of the hood, on a strut tower, a radiator support, fan shroud, or the firewall.
A vehicle can be either Federal/EPA Emissions Certified or California/50 State Emissions Certified. If the VECI label references “California,” “50-State,” “CARB” or “ARB”, then it is a California Emissions Certified model. This is a necessary step in the application lookup process to ensure proper fit and determine the state-mandated aftermarket replacement converter.
The Engine Family Number (EFN) is displayed on every VECI label. This can also be called the Engine Family Code or Group Number.
California and New York have active programs in place to oversee aftermarket parts state regulations. As regulations often change, you should be familiar with your state’s regulations, even if you do not operate in California or New York.
