OZA572-E3 Exhaust Oxygen Probe by NTK NGK 0264

Looking to cure high emissions, poor MPG or a lumpy idle on your classic BMW 3 Series 318is? This genuine NTK OZA572-E3 exhaust gas sensor delivers factory-level accuracy and fast closed-loop control so your ECU can trim fuelling precisely. It is a plug-in replacement with the correct connector and a 730 mm lead, making it the sensible choice when your original lambda probe ages or fails.

We fit these on our own builds and customer cars and the feedback is consistently positive. Expect crisper throttle response, smoother running and cleaner MOT results once the ECU can rely on accurate AFR feedback again.

Why this sensor stands out

  • OE-grade NTK engineering for reliable AFR feedback and stable idle
  • Heated 4-wire zirconia design for rapid light-off and steady readings
  • Correct plug and cable length for a tidy, hassle-free install
  • Helps restore fuel economy and reduce hydrocarbon and CO output
  • Built to withstand heat, vibration and road contaminants
