## Customer Reviews

### ⭐⭐⭐⭐⭐ The right item the price
*by M***T on April 27, 2021*

My VSC light off very happy

### ⭐⭐ 0
*by G***A on January 8, 2026*

They didn't even last two weeks and now he's telling me that the catalysts of bank 1 and 2 are bad 🥲

### ⭐⭐⭐ Poor floor / body seals and I am having new engine codes after replacement.
*by B***8 on November 25, 2022*

Caution! Upon installing I noticed the floor body seals did not like to stay put and could easily be pulled in or pushed out. Installing is a pain as you have to get under the carpet inside the car and find the connectors, not sensor makers fault just odd Toyota / Lexus design. I first thought sensors were great cause the car felt like it had more power but then I got sensor voltage error codes, reset and now have lean error codes. I’m waiting on some denso sensors to replace them. I wish I installed them within my return window. *** UPDATE - I discovered I had a couple vacuum leaks so I probably did not need to buy another set of denso O2 sensors. These may have been ok other than the body seals.
