dont waste your money
well less than 2 months after installation one of the upstream sensors went bad to where after 5 miles of driving it shuts the motor off....unplug said sensor and it runs just fine...keep in mind this is a new crate motor and transmission 2005 Hummer H2 SUT 6.0...10 grand into motor and transmission alone...guess i should have bought the local O2 sensors at 75$ each....

Just as good as OEM at a great savings.
A very good fit. No more check engine light.

Shipping them back they did not work for my Escalade. They were installed truck was taken to auto zone because the sensor wouldn’t clear and they said it was still a bad o2 sensor 😞 but they were packed good and shipping was fast
