Bosch or Denso? I'm in need of new os sensors because my LTs fried my factory ones.
what do you guys recommend, I've read that 13111 are good but can throw some codes

Looks like Denso is better, some notes on them on Camaros here:
http://www.camarohomepage.com/project/part3.htm
Denso is stock in some GM cars...
"The Denso "O2S" is better because its aluminum-oxide "trap layer" covers the sensor element and resists damage to its platinum electrode and a porous, PTFE (Teflon) filter on the sensor's atmospheric side prevents moisture or contaminants from degrading accuracy."
Top is Delphi, Bottom is Denso:

There shouldn't be a price differece. Its the same part. Autopart stores are so dumb sometimes.
Anyway, I run the Denso sensors on my car and they've done better than the Bosch's ever did.

They aren't the same part. They have different length tails on them.
As far as not giving codes, I have been able to run the Delphi O2's without insufficient switching codes, although I would get the code with brand new Densos. As said above, if you order an AC Delco replacement nowadays you will get a Denso. Most don't care about that code and just turn it off.

I've tried both Denso and Delco brands. Both identical and both got me the insufficient code. Denso did only last for a few months. I am now trying the NGK/NTK brand O2s and hopefully they are better.

also i have a friend at a parts store so i got my o2's for like $50 a piece.
regularly i think their $70
Yeah, the wire length. I have extensions so for me I can just get a pair of what is cheaper since the short ones reach. People like the post cat Vette sensors since they have really long tails and you don't need an extension.
13111's here also and i haven't run into any problems yet but all i have is LT's
I got a pair of Bosch 13444 for $29 New off of Ebay, the wire was a little long on the driver side so I used a plastic wire tie. They are working fine for 2 weeks now. I know what people say but $29 was hard to pass up.
