Great product and attention to detail.
Exact part. Fixed my Check engine light. When I was under the vehicle changing it I realized that I had forgotten anti seize. No problem with this part! They had already put some on the threads before shipping. Very nice attention to detail! I love 1a auto's parts. No complaints yet.

Quality Replacement Oxygen Sensor
I installed this sensor to replace a faulty Bank 1, Sensor 1 (pre-cat, driver side) in my 2003 4.7L Tundra. The code is cleared and the sensor seems to be working properly. Once I gained access to the sensor and had the proper tools, replacement was fairly easy and straightforward. I applied some extra antiseize to the threads, as the applied antiseize on the sensor threads was a bit skimpy. Seems to be a good quality part. Ordering and shipping from 1A Auto was easy and fast.

My left upstream 02 sensor needed replacement.So, I went ahead and replaced both upstreams. Worked perfectly. First time I used A-1 auto and it won’t be the last.

Worked perfectly; video made for easy install
I purchased this part to clear the check engine light on my 2004 Tundra. Thanks to the video, I was able to replace the part quickly and easily. The price was also lower than what I was able to find at local auto parts stores. Very happy with my first purchase from 1A Auto and will be coming back to them in the future.
