Our take on the Walker Products 350-64031 Oxygen Sensor

The Walker Products 350-64031 is a direct-fit, 4-wire heated oxygen sensor for engine management, installed with a 22 mm wrench. It is a vehicle-specific part, so it fits only the applications Walker lists for this number. At $91.99 at O'Reilly Auto Parts as of November 3, 2026, it sits at the top of its recent range among the 4 stores listing it new, so it is not a bargain price right now.

Questions and answers

Is $91.99 a good price for this sensor?
It is the best new price among the 4 stores listing it as of November 3, 2026, but it is at the top of its recent range. Waiting for a dip below this level is reasonable if the car is not throwing a code yet.
Will this fit my car?
Only if your vehicle is listed for part number 350-64031. It is a specific-fit sensor, so check the application list by year, make, model and engine before buying.
Do I need a special tool to install it?
A 22 mm oxygen sensor socket or a 22 mm wrench works. Soak the old sensor with penetrating oil first, and use an anti-seize compound on the threads if the new sensor does not come pre-coated.
Is this a heated sensor?
Yes. It has 4 wires, which means a heated element plus signal and ground, so it reaches operating temperature faster than an unheated sensor.
When is this sensor cheapest?
Prices across the 4 stores move, and $91.99 is currently the lowest new price but near the high end of the recent range. Check back for drops, especially outside peak repair seasons.
