The Porsche O2 / Oxygen Sensor (post Cat) with OEM number 98760612400 is a used genuine component removed from a donor vehicle. This downstream oxygen sensor monitors exhaust oxygen levels after the catalytic converter on 2.7L–3.6L H6 naturally aspirated engines. A failing post-cat sensor often triggers the check engine light and can cause an emissions test failure.
