4-Pack O2 Oxygen Sensors Upstream & Downstream For Mercedes-Benz E320 E430 1998-2000 V6 V8

Got a check engine light on your 1998-2000 Mercedes E320 or E430?

Probably an O2 sensor.

This kit comes with all four—upstream left and right, downstream left and right.

They're direct-fit, narrowband sensors with 4 wires each.

Made with a zirconia sensing element and a 310 stainless steel sleeve, so they're tough.

They've got triple sealing tech (rubber and dual laser welding) to keep exhaust out.

Wiring harness lengths vary: 387mm for upstream left, 544 for upstream right, and 237 for downstream.

Heated, pin-type terminals.

Replaces OEM numbers 0005406117, 0005407117, and others.

Comes with a 1-year warranty.

If you're throwing a code, this kit covers all bases.
