## Customer Reviews

### ⭐⭐⭐⭐⭐ They were not damage
*by A***R on June 11, 2025*

My parts came right on schedule

### ⭐ 2 sensors failed, DON'T BUY
*by J***L on March 4, 2025*

Two sensors failed....more specifically the heating elements in both down stream sensors. Before I replaced my sensors the only issue I had was my O2B2S2 failed. Now magically after replacement both O2B1S2 and O2B2S2 has been failing and not activating properly. I won't buy these again and sadly, it's well past the return window. I'm not happy at all with this product.

### ⭐⭐⭐⭐⭐ Awesome
*by C***E on April 5, 2025*

Perfect fit, fixed issue
