Product Details

The NGK (NTK) 21053 oxygen sensor, also called an O2 sensor or lambda sensor, is an OE-type heated downstream sensor. It sits after the catalytic converter in the exhaust and monitors converter output. This gives the engine computer the feedback it needs to keep emissions and fuel economy in check.

Key Features:

  • Heated design: Reaches operating temperature quickly, which helps improve fuel economy and reduce emissions.
  • Dual-coated platinum element: Increases longevity and delivers fast response time.
  • 4-wire construction: Signal, ground and two heater wires.
  • 18mm thread diameter: Metric threaded mounting.
  • OE-specified connector and hardware: Made for easy installation.
  • OE-type fit, form and function: NTK is a major supplier of original equipment oxygen sensors.

A worn or failing oxygen sensor can lead to higher fuel consumption and increased emissions. Replacing it with a quality NTK sensor helps restore proper closed-loop engine management.

Excellent product. Prompt delivery. Will continue use Autoplicity when needed.

Found the parts I needed for my vehicle's TPMS system that I could not get anywhere else. They were a better price than any of the other online stores and got my order shipped out in a timely fashion.

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.

Best price I could find on the net and super fast shipping.

Great Prices and great communication. I received notification as soon as I made the order, and when it was shipped out, along with a Tracking number. They were very quick to mail it out too.<br><br>Thanks<br><br>Order number 13029

Very fast shipping, lowest prices on the web.

Easy to use great product and fair pricing
