Are they a ok one to use? I saw Rockauto has the Denso O2 sensors for 33 bucks. Here'* a pic of it. Or is Delco strongly reccomended?

well for about $15 more you can get a Delco, so... for a 50-100K mile part, i would spend the extra $15

For a part that pretty much dictates how ya Bonne performs,I'd spend the extra money

While Denso is a solid brand in itself (their spark plugs are good schtuff)... I'd stick to Delco.

Alrighty..... I will get the AC.

How many of those that have posted have used a Denso? I'd use a Denso over a AC Delco any day. Dont get me wrong AC Delco works well but Denso > AC Delco. Is ir worth the extra money? Its up to you...

Do you have any technical data to back up that Denso or AC Delco is proven better?, More reliable? Quicker flip flop times?

id just like to point out that i used denso o2'* on my old mitsu and never had another problem with emissions again, they seem decent and good priced.

common consenus here, is that the AC Delco O2s are the best bet for us bonneville drivers, many people have had reliability, logevity and DOA issues with other brands, and it seems that everyone (or atleast nearly everyone) has terrific luck with Delco parts in this application

Have either of you used one in a Bonne, though? Seriously, I want to know. If I can save a few bucks and get a good part, I'm all over it! It would definitely be nice to have options since some of us can only get the Delco'* through mail order. Nobody here locally seems to stock them.
