Product Details

The NGK (NTK) 21043 oxygen sensor, also called an O2 sensor or air-fuel ratio sensor, is a heated, narrow-band replacement sensor. It monitors the oxygen content of the exhaust and sends continuous feedback to the engine control unit (ECU). The ECU uses that signal to adjust the air-fuel mixture. This supports engine performance, fuel economy, catalytic converter efficiency and low emissions.

Key Features:

  • Highly sensitive zirconia sensing element with an internal ceramic heater for fast light-off and response
  • Dual-coated platinum interface for durability and quick response
  • Contaminant-resistant overcoat helps protect the element from poisoning
  • OE-style, water-resistant connector and harness hardware for easy installation
  • Tested for vibration and thermal shock

Specifications:

  • Sensor type: narrow band, heated
  • Number of wires: 4
  • Thread size: M18 x 1.5 mm (18 mm diameter)
  • Mounting type: screw-in (threaded), not flanged
  • Wire length: approximately 27.5 to 27.75 in. (699 to 703 mm)
  • Connector type: OE-style, pin terminal
  • Wiring harness included: yes
  • Grommet included: no

This sensor is built to meet or exceed OE form, fit and function. It is a direct-fit replacement that helps restore proper closed-loop fuel control.

The search function wouldn't find the Pertronix part number 1847A with only the 1847 entered in the search field. I had to enter the whole part number. Less is more in a search, so if you fixed that, more people might find the part they want and order it.

I finally had time to install my part. The steering wheel hub was exactly what I needed at a great price and delivered promptly. Thanks for the great service.

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

Great communication, super fast shipping, and product just as described. Very happy, thank you.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

I would not hesitate buy from Autoplicity again!!! A+++

Autoplicity had the best price anywhere! I looked everywhere for the airaid intake system and they had it in stock. Great company!

I wanted to order a couple of difficult to find accessories for my new Jeep Wrangler. Autoplicity not only had the items I was looking for, but had them at a very reasonable price. The two items were shipped separately but arrived in short order. Thanks to Autoplicity for filling my order #7860 of 3/26/12 quickly and accurately. See you again soon.

Excellent price on kirkey seats! I will be buying from them again. Thanks for the prompt service

Best prices on the web, shipping charges were as well, ordered on Tuesday received on Saturday of same week!!
