Description

This NGK Direct Fit 4-Wire A/F Sensor, part 24831, is an NTK direct-fit air-fuel ratio sensor for the 2010-2012 Subaru Legacy application named in the title. Per the stored NTK copy, wideband oxygen (air-fuel ratio) sensors produce a linear output signal that allows the ECU to determine exactly how rich or lean the engine is running and make continuous, precise adjustments of the air-fuel mixture to stay closest to stoichiometric.

Features:

  • NTK is the world's largest supplier and manufacturer of original equipment oxygen sensors, per the stored NTK copy
  • Extensively tested during manufacturing to guarantee quality and reliability that meets or exceeds OE specifications, per the stored copy
  • NTK uses state-of-the-art technology enabling control of the ceramic used in the sensor from raw material to finished product, per the stored copy

Fitment:

  • 18 entries in the stored fitment list: Subaru Legacy 2010-2012 and Subaru Outback 2010-2012 applications - the legacy title names the Legacy application only and was kept verbatim (see Fitment Notes)
  • Confirm by part number 24831 before ordering
