Ensure that all components are free of contaminants before installing. Contaminants may cause premature wear and reduced component service life. |
Note: Disposition and Recycling - Common components of exhaust aftertreatment devices include, but are not limited to, cordierite, silicon carbide, iron zeolite, vanadium, platinum, and palladium. After the devices are used in an engine exhaust flow they can include some by-products that result from combustion. Follow applicable Federal, State, and local regulations when handling or discarding used aftertreatment devices.
