Over repeated thermal cycles, oil consumption, or minor ignition misfires, unburned fuel ignites inside the shell, causing substrate fracture and washcoat poisoning. Once the internal honeycomb breaks apart or melts, exhaust backpressure spikes while HC, CO, and NOx conversion drops below threshold.
