Our take on the Walker Products 250-24018 Oxygen Sensor

The Walker Products 250-24018 is a direct-fit oxygen sensor for engine management, sold as a replacement for a failed upstream or downstream sensor. It is a four-wire heated sensor aimed at DIY and shop repairs rather than performance tuning. At $27.11 at CarParts.com as of November 3, 2026, it sits at the low end of the $27–$45 range the four stores show.

Questions and answers

Is this a direct-fit or universal sensor?
It is sold as a direct-fit replacement with a factory-style connector for the listed application. Verify your year, engine and sensor position before ordering.
Is $27.11 a good price?
It is the lowest of the four stores and near the bottom of the recent $27–$45 range. Waiting is unlikely to save much.
Will it fix my check-engine light?
If the code points to a slow or dead oxygen sensor, yes. If the code is for a heater circuit or a lean condition, diagnose first; the sensor may not be the cause.
Does it come with a socket or hardware?
No. It is the sensor alone, so you need an oxygen sensor socket and any anti-seize you plan to use.
How long does installation take?
On most cars it is a 20–40 minute job with a sensor socket. Rusted threads on older cars can turn it into a longer repair.
Where is the Walker Products 250-24018 Oxygen Sensor cheapest?
At CarParts.com, for $27.11, 34% under what the other stores charge, as of our latest check.
