Product Details

The NGK (NTK) 21048 oxygen sensor, also called an O2 sensor or air/fuel ratio sensor, is a direct-fit replacement. It monitors the oxygen content of the exhaust gas. The engine computer (ECU) uses that reading to adjust the air/fuel mixture.

Key Features:

  • Designed to OE specifications for a direct-fit replacement
  • Factory-fitted OE connector, so no splicing is needed
  • Flange mount with push-pull output type
  • Rated for an upper temperature of 1000°C
  • Metal construction
  • Tested during manufacturing for quality and reliability
  • Includes installation instructions
  • Cross-references include ACDelco 213-1528, 213-1552, 213-1641, 213-1688, 213-1692, 213-800, 213-816 and 213-818; GM 12559848, 12561777, 12562621, 12567163, 12573168 and 19209807; Bosch 13178, 13780, 13787, 15280, 15895 and 15902; Delphi ES20094 and ES20320; BWD OS1473; Spectra Premium OS5201; and Standard Motor Products SG720

A new oxygen sensor helps keep the air/fuel mixture correct. This can lower emissions, improve fuel economy and engine efficiency, and extend catalytic converter life.
