Abstract: A boss configured to mount a nitrous oxide sensor in an exhaust conduit is disclosed. The boss includes a first tier configured to contact with an exterior surface of the exhaust conduit, the first tier defined by a first diameter and a first height. The boss also includes a second tier extending from the first tier. The second tier is configured to be disposed within an interior space defined within the exhaust conduit. The second tier is defined by a second diameter and a second height. Further, the second diameter is sized smaller than the first diameter. The boss further includes a condensation protection feature configured to direct condensation away from the nitrous oxide sensor.
