HOP Oxygen Sensor 12675980 provides precise replacement for Buick, Cadillac ATS/CT6/CTS and Chevrolet models.

Does your vehicle show engine fault light on, idle instability, weak acceleration, or abnormal fuel consumption? These typical symptoms usually indicate aging oxygen sensors causing air-fuel imbalance. The oxygen sensor monitors exhaust oxygen content in real time and feeds signals to the ECU to precisely control injection, ensuring combustion efficiency and emissions compliance. OEM number 12675980, perfectly fits Buick Cadillac ATS, CT6, CTS and other Chevrolet models (compatible with 12652845, 12669867, 12677120, 27016). Installation requires using a dedicated socket to remove the old part to avoid thread damage; apply anti-seize/anti-galling lubricant to the threads and tighten to standard torque to prevent leaks affecting signal accuracy.
