What are good o2's to run. I have put new headers on & thought about putting in new o2's since I have been running leaded gas through the old ones. Is the boasch o2's any good, that is all the parts stores sell around here. I don't think I'll be running leaded gas through them any more. But maybe when new heads go on. How about those denso's are they good?

I have bosch and those too are going bad on me again. I would suggest looking into the denso corvette rear o2's for use in the f-body front locations. Densos also seem to be far more lead tolerant, but theyll eventually die from running too much leaded gas too.

Is this the right #'s 234-4025 L 234-4087 R Are these correct denso's. Are the wires longer than stock wires like the bousch 13444's? I checked on oem O2's they were 150.00 retail, thats to much.

I actually switched to the bosch corvette rears 02's to put in my fronts cause my slp extensions were failing everything up and the vette ones didnt work for me either. I am probly going to do a closed loop on them.

I don't know that mine are bad. When I went to the dyno last time & got it tuned, the A/F gauge on the dyno was not working properly so we could'nt get a correct reading. But the plugs are pretty white when I took them out yesterday. I also have ran racing gas through it mixxed 50/50 with 93oct. I also just installed FLP Lt's & figured why not. Need GOOD advice.

My original O2's got fouled to all heck and after some minor searching I realized I should be running O2's made for the rear C5 bank. Ended up with Bosch part #13111. I put them in and my horrid problems went away immediately. Am I going to end up replacing them with something else? I havn't happened across this claim before.
