In a method of making a gaseous emissions treatment component, a ‘green’ ceramic mix is extruded through a die to form an extrusion having cells extending along the extrusion, the cells being bounded by walls dividing adjacent cells from one another. In concert with the extruding, metal is fed through the die with the extruded mix. A length of the extrusion and associated metal is then cut off and fired to form the component.

A shield for a diesel exhaust fluid injector is mounted in an opening in a side wall of an exhaust gas aftertreatment system of an internal combustion engine. The diesel exhaust fluid injector is configured to inject diesel exhaust fluid in a direction generally normal to the side wall into a mixer positioned in an exhaust gas stream. The shield includes a first portion extending axially and a second portion extending radially inwardly from the first portion.
