Mustang Emission Test Decal
Mustang emission decals display information from the factory emissions test, as well as the engine family or test group, displacement, model year, fuel type, and catalyst information. Over time, these decals can tear away, fade, or get covered up. Most emission decals come with an adhesive backing and can be easily installed under your Mustang’s hood.
