Upgrade your Audi, VW, or Porsche with the Oxygen Sensor Front Lambda for Audi A3 A4 A5 A6 A8 Q5 Q7 Quattro from IWOKPHD. This upstream/front O2 sensor monitors the air-fuel balance in real time, helping your engine achieve precise combustion, lower emissions, and better fuel efficiency.

It’s a ready-to-install, tested replacement that’s engineered to match the performance of the original part, helping you maintain optimal engine operation and compliance with current emission standards.
