NTK Oxygen Sensor 4 Wire 530mm Cable - OZA341-F2

NTK Oxygen Sensor - OE-matching quality, fit and performance

NTK 02 Sensor units are precision manufactured to the highest quality and with maximum durability in mind. The dual-coated platinum element offers increased longevity and resistance from fouling and breaking down over time as seen on other cheap replacement 02 sensor options. The three-stage element overcoat also helps to protect against wear as well as contamination from exhaust gases while the pure alumina ceramic filters exhaust gas for an accurate reading from your oxygen sensor. Fast light-off times also helps to decrease emissions so your car is gentle to the planet fuel bills are decreased. NTK O2 Sensors are designed and tested against OE quality standards to ensure a great fit just like the original and matched if not better performance and longevity than the factory fitted sensor. With over 80 years of automotive expertise under their belt serving both OEM applications and the aftermarket, NTK knows what goes into great replacement sensors.

Gone are the days of carburettors and points ignition, when it comes to running modern cars pretty much everything is electronically calculated, adjusted, transmitted and actuated by your ECU or ECM. Whilst the ECU is able to do all the clever calculations and literally operate your car, it relies on the switches and sensors to transmit all of the necessary information it requires in order to allow the ECU to do its job including oil pressure, fuel pressure, coolant temperature, A/C pressure, power steering pressure and even fuel temperature. Behaving as your car's nervous system, faults in automotive switches or sensors can cause issues such as a lack of power, poor efficiency, overheating, internal engine damage or a car that won’t run, start or idle at all. Whilst your switches and sensors will take care of engine vitals such as oil pressure indication, coolant temperature and oil temperature, various switches and sensors also allow the operation of some of the extra features you wouldn't want to be without.

Subjected to harsh under-bonnet conditions, just like other components of your car, old switches and sensors can fail over time and give incorrect data or no data at all to the ECU. Often these issues will flag up a check engine light on the car which is useful if you have a code reader, however sometimes the issue will remain a mystery. We recommend testing your suspect sensors with a multi-meter to track down the issue. By testing for continuity, voltage and resistance, you can confirm the issue and get stuck into fitting a replacement switch. By fitting quality replacement switches and sensors to your car, you can drive with the confidence that your car will run to its maximum potential in terms of power, efficiency and longevity and that all of your car's features will continue to operate correctly for time to come.
