Check engine light on?

Could be your O2 sensor.

This pair of downstream oxygen sensors is exactly what you need for a bunch of GM vehicles with the 3.6L V6—think Impala, Acadia, Terrain, Enclave, and more.

They’re direct-fit, so no splicing or guesswork.

Just plug ’em in and clear that code.

Each sensor has 4 wires, a 500mm lead, and a black female connector.

Solid build, easy install, and backed by a 1-year warranty.

No brand name on these, but the fit and function are spot on.

Get your fuel trim back in line and your emissions in check.
