Product Details

The NGK 21541 oxygen sensor (also called an O2 sensor or lambda sensor) is a heated, narrow-band, switching zirconia sensor. It measures oxygen in the exhaust and sends that reading to the engine computer, so the computer can keep the air/fuel mixture correct. NGK/NTK is a major OE oxygen sensor supplier, and this sensor is built as a direct-fit replacement.

Key Features:

  • Heated, narrow-band switching zirconia design
  • Precision-manufactured sensing element made with premier technical ceramics
  • Factory-fitted OE-style connector for easy installation
  • Thread-in mounting with M18 x 1.5 thread
  • 7/8 in. (22 mm) hex size
  • 3-wire design with a wiring harness length of about 15.3 in.
  • Tested during manufacturing for quality and reliability

A new oxygen sensor helps the engine run efficiently. It supports lower emissions, better fuel economy and longer catalytic converter life. A worn or failed sensor can hurt all three.

I ordered the part from Autoplicity and it arrived in time and is a great product<br>

Autoplicity IT help desk was great in getting the order done. I had problems with my computer and the IT person worked things out so the order could be processed.

Best Price i could find for some nice foglamps. easily navigable website.
