Product Details

The NGK 21556 oxygen sensor (also called an O2 sensor or air-fuel ratio sensor) is an OE-style, direct-fit replacement. It monitors the oxygen content of the exhaust and sends that signal to the engine computer. The computer uses it to manage the fuel and ignition systems, which supports efficient combustion and emissions control.

Key Features:

  • Heated, narrowband design with a highly sensitive zirconia sensing element
  • Ceramic heater for faster response times
  • Thread size: M18 x 1.5 mm (18 mm), screw-on mounting
  • Wiring harness included: 520 mm (20.5 in.) wire length with OE-style pin connector
  • Corrosion- and abrasion-resistant, robust construction
  • Meets or exceeds emission standards
  • Backed by a limited 1-year warranty

Cross-references: ACDelco 213-1559, Bosch 15130, BWD OS2213, Spectra Premium OS5461.

NGK/NTK is a leading supplier of oxygen sensors. The OE-style connector and direct-fit design make installation straightforward, and the sensor helps keep the engine running efficiently and cleanly.

nice.

Quick and easy

Quick and easy. Found the part using proper terminology right away

Good company I'm pleased

I received the product within a week and it was exactly what I needed.

Easy, clear, fast !!!! I only put one star for satisfaction because I won't know until the product is installed and I can check it for fit and form. I suspect it will be satisfactory since it replaces one I previously purchased. ..... however I wish it would last longer than the last one ...... approximately 4 years.

Fast and easy. Thank you.

Best prices online for a locker and pretty fast shipping too!

Awesome place to get parts from. Went looking all over the city of houston to find a certain light everyone was sold out tried online two "Huge chain name" places were also sold out. Stumbled on Autoplicity and they had just what I needed!

Found part quickly. Price was competitive.
