Product description
ACDelco builds this Downstream O2 Sensor to the original equipment envelope, so it bolts into the original equipment location using the factory hardware. The substrate loading is sized to bring the system through a Federal EPA test with margin, not just barely. A value-tier fitment for a sensible repair on an older vehicle, not a compromise on safety.
