## Description

Denso 234-4168 Downstream Oxygen Sensor with 4-Wire 13.7” Harness

Review: Had this dealer installed and it has worked flawlessly since then. Much cheaper price than what the dealer would have wanted and OEM specified.
Review: fit perfectly, the cable was a little thinner then the OEM, I assume it was upgraded technology in the heat resistance material, or at least I hope so!! I've been told DENSO is the maker of OEM Toyota o2 sensors, so I had no issues purchasing this one. so far it has worked like a charm! it was a lot cheaper then OEM, desertcart Prime shipped it free so it was totally worth the chance. It was difficult to get my 15 year old factory o2 sensor out but once I did this one went right into place and connected right into the factory wire connector. My check engine light went off for the first time in 4 years.
