I specifically ordered Bosch 13111's and that is all they came back with. Any chance they are talking about different brands of the same style, such as Denso, or AC?

No , I specifically asked about that and they said they were all Bosch

Hey Orion! You were right; My car runs SO strong now that I had a tune performed. What a difference a Tune makes, huh? I also through on an LS6 intake for good measure before the tune and it really pulls hard & smooth between 5,000-6300 rpms....

sorry guys for the question but im doing a install of lt's and a ory and i just wanted to make sure i got this right. what you guys are doing is replacing your front 02 sensors with these 13111's instead of an extension. and for the ones after the cat they are tuned out. is this correct.

Im in the same boat as you, gonna put my headers on after the snow melts. but from what I have read you are right, 13111's up front, tune out the rears.

Yep Guys, you got it right. I just finished my project about 4 weeks ago and it's that simple; Tune out the rears & 13111's in the front. BUT the SES light will likely come on either way UNTIL you have it tuned. Good luck and let us know how your install (of the LT's) goes....

im picking up a set of these in the next couple days.
just to make sure, the bosch 13111 is the rear corvette o2 sensor, but we use it as the front o2 sensor. since i dont have cats the rear o2 sensor will be unused, but screwed in just to plug the hole.
