Direct Fit Oxygen Sensor (SG708) For Chevy & GMC Trucks: Silverado, Avalanche, Escalade

Is your Chevy or GMC throwing a check engine light?

This oxygen sensor—technically an Air/Fuel Ratio sensor—is a direct, straightforward swap to get your engine running right again.

It's made by Well Auto (part number OX-GM-708) and matches the OE spec perfectly.

This little guy fits a ton of GM trucks and SUVs from the early to mid-2000s, including the Silverado, Avalanche, Suburban, Escalade, and even the Astro van.

It sits in the engine compartment, has a 4-wire setup with a mini-blade terminal, and is a breeze to install.

It's a brand new, direct-fit part, so no splicing or messing around.

Just plug it in, clear the code, and enjoy better performance and fuel economy.

Comes with a 1-year warranty, too.
