Oxygen (O2) Sensors are used in modern automobiles to control the fuel and ignition systems to optimize a cars performance in the areas of emissions and fuel economy. Sensors are located before and after the catalytic converter to check on the amount of oxygen in the exhaust. The sensor sends signals to the cars on-board computer, which then can adjust several variables, including air/fuel ratio and timing, in order to bring the engine into the optimum operating range.

Each NTK Oxygen (O2) Sensor is:

  • Extensively Tested During Manufacture to Guarantee Quality and Reliability
  • Supplied With a Factory-Fitted OEM Connector for Easy Installation
  • Precision manufactured with a sensing element incorporating NTKs premier technical ceramics

Oxygen (O2) Sensors should be tested at each tune-up. Failed or worn out oxygen sensors can cause:

  • Failed Emission Tests
  • Increased Fuel Consumption
  • Failed Catalytic Converters
  • Poor Driveability
  • Increased Emissions

Excellent business. This is my second purchase and there will be more! I ordered my parts over the holiday weekend and they mailed them the Tuesday after Labor Day. The absolute BEST pricing you will get. You will not find a lower price else ware. The shipping doesn't even take forever like most places you get great pricing. Communication is excellent, the site is very easy to use and navigate. I will be doing business with Autoplicity.com many more times and highly recommend them.

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews.  I decided to take the chance and I am very glad I did.  I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm.  The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago.  I was expecting a model that had been sitting on a shelf for the last year and needed to be updated.  That was not the case.  I will definitely order from Autoplicity again in the future.
