4-Pack Oxygen Sensor Set For 2005-2021 Chrysler 300 – Upstream & Downstream

Alright, if your Chrysler 300 is throwing a check engine light or just running a bit off, these oxygen sensors might be the fix.

This is a set of four brand new, direct replacement O2 sensors.

They fit a huge range of Chrysler 300s from 2005 all the way to 2021, covering engines like the 2.7L, 3.5L, 3.6L, 5.7L, 6.1L, and 6.4L.

They replace OEM numbers 234-4274, 234-4545, and 234-4547.

These are the unbranded version, but they're new and ready to go.

They're 500mm long and go in both upstream and downstream positions.

Easy to install – just unplug the old one and screw this one in.

No fancy UPC here, just a solid set of sensors to get your Hemi (or Pentastar) purring again.
