4-Pack O2 Oxygen Sensors (Upstream & Downstream) For Chevy Silverado & Cadillac Escalade 6.2L

Is your Check Engine light on and pointing to an oxygen sensor issue?

Here's a solid way to get it sorted.

This is a complete set of four (yes, four!) oxygen sensors from CCIYU, designed for vehicles with the 6.2L engine, like the Chevy Silverado and Cadillac Escalade.

You get both upstream (front) and downstream (rear) sensors, so you can replace all of them at once for peace of mind.

They're direct-fit replacements, meaning they're built to plug right in without any splicing or messing around.

Each sensor has 4 wires and comes in two lengths—530mm and 700mm—to match the factory locations.

They cross-reference with a bunch of numbers like B234-4255 and B21546, so you can be sure they're the right ones.

They're brand new and come with a 1-year warranty.

Swapping out old, lazy O2 sensors can improve your fuel economy and engine performance.

So grab this 4-pack and get your GM truck or SUV running like it should again.

Easy peasy.
