Product Details

The NGK (NTK) 21559 oxygen sensor, also called an O2 sensor or lambda sensor, is a direct-fit replacement sensor. It reads the oxygen content of the exhaust gas and sends that signal to the engine control unit (ECU). The ECU uses it to adjust the air/fuel mixture for efficient combustion. NTK is a leading OEM supplier of oxygen sensors, and each sensor is individually tested.

Key Features:

  • Narrow band, heated oxygen sensor with a zirconia sensing element and a ceramic heater for fast response
  • 4-wire design with a 17 in. (430 mm) wire harness
  • Non-flanged, screw-on mounting with an M18 x 1.5 mm thread
  • OE-style connector for plug-in installation without cutting or splicing
  • Built with OEM-approved materials and meets or exceeds OE specifications
  • Waterproof, durable construction
  • Limited 1-year warranty

Cross-References / OE Numbers: GM 12580466, 12589321, 12597989, 25180901, 25182983; ACDelco 213-3206, 213-3533, 213-3544; Bosch 15137, 15139, 15150; Delphi ES20352; DENSO 234-4236, 234-4337, 234-4773, 234-4774; Spectra Premium OS5485; CARQUEST 75-3689, 75-3691, 75-3700.

A new oxygen sensor can help lower emissions, improve fuel mileage and engine efficiency, and extend catalyst life.

I am very pleased with the level of service I received not to mention the great price they offered on the item I purchased.

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.
