The pigtails are different though, so if you do buy a set be prepared to cut and splice.

Damn so close, but no cigar for me...I am having somewhat of the same problem right now, Bank 1 is lean... I'm not boosted but bank 1 is running lean after I changed out the o2's w/ the Bosch ones. Took it up to my tuner and he logged it and then we swapped 'em and bank 2 is still perfect but bank 1 got better (it was showing +25 and now its at +8). So we adjusted the tune a little and I was on the way back home and then the truck started bucking and running real rough when on the gas. Logged it and the bank 1 sensor was showing 45mV and not switching at all so I disconnected it to make it to my bro. house 70 miles away still have to make it 35 more miles to the house. Can't figure this **** out. I guess I'll do more trouble shooting tomorrow...Zed

Update on mine, I made a blockoff plate for the EGR and no change, so it's not an EGR leak. Next step for me is to R&R the passenger side header to see if there is a damaged gasket.
