Oxygen Sensor Upstream Air Fuel Ratio for Audi A8 RS7 S6 S7 S8
Upgrade your Audi with the IWOKPHD Oxygen Sensor Upstream Air-Fuel Ratio, a heated upstream O2 sensor designed for 2013–2018 Audi A8, RS7, S6, S7 and S8 models. This sensor accurately monitors the exhaust oxygen level to help the ECU balance the air–fuel ratio (lambda) for cleaner emissions, better fuel economy, and smoother performance. It supports a wide range of OEM references, including 4H0906262P, 2345161, 27055, 06K906262AF, 079906262R, and 8V0906262, providing a reliable, plug‑and‑play replacement without guesswork. The upstream sensor uses a piezoelectric element and is heated for fast, stable readings even after cold starts, delivering consistent performance in demanding driving conditions.
