Product Details

The NGK NTK 21537 Oxygen Sensor (also called an O2 sensor or lambda sensor) is an OE-type replacement. It monitors the amount of oxygen in the exhaust stream and sends that signal to the engine computer. The computer uses it to keep the air-fuel mixture correct, which helps emissions and fuel economy. NTK's parent company, NGK, supplies original equipment oxygen sensors to vehicle manufacturers.

Key Features:

  • Designed for OEM applications, with a factory-fitted OE connector for plug-in installation
  • Sensing element made with NTK technical ceramic and an integrated heater. The heater brings the sensor to operating temperature quickly, so closed-loop operation starts sooner and cold-start emissions are lower
  • Protective coating on the element for durability
  • Tested during manufacture, including a multi-step process for quality and reliability
  • Mounting type: flange mount, with a push-pull output type
  • Includes the oxygen sensor and installation instructions

A new oxygen sensor can help restore fuel economy and smooth running, and it helps the engine meet emissions requirements. The OE-style connector allows a direct plug-in installation with no cutting or splicing.

After searching for the best prices for the product that I wanted, I ended up with Autoplicity. I quickly got a response that my product has just been shipped and I am very impressed that Autoplicity is giving me an incentive to write a review on them. This tells me that this company is very concerned with the satisfaction of their customers. I am currently waiting for the order to arrive, but so far, I am extremely confident and happy with Autoplicity!

Quick and easy

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984
