La entrega excelente y el repuesto de calidad
Muy buenos los sensores de calidad
Reviewed in the United States on March 22, 2026 by Exelemte
Fit and working so far
I recently installed the Hqpacfy Oxygen O2 Sensor set (upstream and downstream) on my 2011 Cadillac CTS, and overall, they’ve been decent so far. The sensors fit properly without any issues, and installation was pretty straightforward with no modifications needed. After replacing the old sensors, the check engine light went off, and the car seems to be running smoother than before. Fuel efficiency may have improved a bit, but nothing dramatically noticeable yet. The build quality seems okay, not quite OEM level, but reasonable for the price. Time will tell how they hold up long-term, but for now, they’re doing the job as expected. Overall, a solid budget friendly option if you need to replace your O2 sensors without spending a ton.

Good Quality, Accurate Sizing
Great value on well manufactured, quality parts. They fit & function exactly like the OEM parts we have used in our shop. The size is exact & they install perfectly. They are put together really well, and appear durable. As for how long they function, only time can answer that question.
