I will ALWAYS use 1a auto!
These o2 sensors came in perfect condition packed with plenty of bubble wrap to make sure they weren’t damaged and worked efficiently. They even went as far as to put a little bit of anti seize lubricant on the threads of each sensor! Very nice touch! I love this company and their dedication to providing the BEST of the best! Keep up the great work guys!

Buick Custom LeSabre 2005 Fits
The video 1AAuto provided helped me put this new part in my car effectively (Buick Custom LeSabre 2005). Be warned though, the video shows an older Buick pre-2000. In the "newer" Buicks like mine, the whole engine is about 6 inches further into the car frame.

This means I had to buy a 3/8" swivel for my ratchet set in order to reach the O2 Sensor with a tool. It is doable on the newer Buicks, you just need an extra piece. Swivels can be bought at a typical hardware store for around $15.

Thank you 1AAuto for listing this replacement part at a lower price than other companies. Considering I am an English Teacher and always trying to cut corners for money, I appreciate it.
