I was working on installing an atp downpipe and it was really the second worst thing I've ever done while working on a car took me 5 fucking hours to remove the stock downpipe. I digress neither of the two o2 sensors wanted to come loose and I eventually coaxed them by tightening a little the loosening more and on both the threads were badly damaged. My car only has 30k miles and the sensors have never been removed prior. Can I warranty the sensors with ford? Also I need two o2 sensors so if anyone has some let me know.
