Title: Hummer H3
Review: Was hard to get the OEM O2 sensor off.. found it easiest to lay under my H3 wheel well and grab that sucker and just pull on the wrench!!! My O2 sensor tool cracked so i had to improvise... But this went in no problem, my vehicle runs like a champ... was nothing wrong before i'm just coming up on 100,000 miles and was swapping parts out!
