Product Details

The NGK (NTK) 23140 oxygen sensor, also called an O2 sensor or air/fuel ratio sensor, is an OE Identical replacement. It monitors the oxygen content of the exhaust stream and sends that signal to the engine computer. The computer uses it to adjust fueling, which helps keep fuel economy and emissions in line with the original specification.

Key Features:

  • OE Identical design, made by NTK, a major supplier of original-equipment oxygen sensors
  • Heated, 4-wire sensor that reaches operating temperature quickly to support fuel economy and lower emissions
  • Dual-coated platinum element for long service life and fast response
  • 18mm thread diameter
  • Wire length of about 18 in. (457mm)
  • OE-type connector and attaching hardware for straightforward installation
  • Threaded mounting style

A worn oxygen sensor can lead to poor fuel economy, rough running and a check engine light. Replacing it with a quality OE-spec sensor helps restore proper engine management and emissions control.

Best pricing I found anywhere on the part I needed, quick shipping, no hassle. Definitely going to be a repeat customer.

Installed a 5th wheel hitch in a F150 with a 5 1/2' bed. Autoplicity had the Sidewinder hitch I needed to put the swivel under the camper insead of at the hitch,also at a lower price than competitors with extremly reasonable shipping $14.38. I Placed the order on a Friday and the item shipped the same day. Very happy with the product and fast shipping.

Autoplicity had an item my vendor had on backorder for weeks in stock and shipped it very quickly. I'm glad i found this place on the web, and will be looking forward to doing business with them in the future!

Claimed to give me a military discount I purchased online after hrs and it was 1.79 more some discount that was offered.

SUPER EASY TO ORDER, CHEAPEST PRICES!! WILL BE ORDERING FROM THEM AGAIN!

They had the product I wanted at an excellent price. I was very pleased because my order came much faster than I thought it would.

Its amazing the prices Autoplicity is able to offer some of their products at. The product i ordered was consistently msrp on every site i searched through, yet autoplicity had it for $10 less. Lowest price along with a attractive and intuitive website is a win in my book. Having it shipped in less the 24hrs is another bonus
