GMC Acadia / Terrain / Chevy Malibu / Blazer / Buick Regal Downstream Oxygen Sen

SKU GMC-O2
Price

$34.99

The downstream oxygen sensor monitors exhaust gases after the catalytic converter to confirm it's working properly and help the computer manage emissions. A worn sensor can trigger a check engine light or a catalyst efficiency code.

This sensor fits the GMC Acadia, Terrain, Chevy Malibu, Blazer, and Buick Regal lineup, matching OE part number 12627140.

Matching the OE number ensures accurate sensing and reliable catalytic converter monitoring after installation.

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
