I have found with with my HP Tuner wwhy I cant get my Fuel trims right.I have been running rich for so long now My O2 sensors are just Fowled with Black soot .I got one from Autozone tonight and the thing doesnt even look like mine,It is alot smaller.the Bosch Part Number is 13444 is this Correct?

Thanks!

 

Corvette Rear O2 Sensors:

Bosch 13111
Denso DEN 234-4087

I wouldn't screw with stock F-body ones, just go
ahead and switch to the higher wattage heaters.
Take the other one(s) back.

 

13444 is the correct # for fodies.

Hey, jimmyblue I have never heard of using corvette O2s, what is the bennefit of this? thanks!

 

13111's are more accurate with LT headers.

 

Oh Really?I have LT's.Should I go this route?13111's...

 

Darn I should Have asked you guys before hand!So the 13111's are more accurate....Thanks

 

Well got my 13111 Bosch o2's in Today I let you know how it looks tomorrow....

 

the 13111 bosch O2 sensors are actually rear corvette sensors... so the wire is longer... people sometimes have problems w/headers using stock length O2s and an O2 extension... they get heater SES lights... from my understanding it seems that the 13111s draw more power since it's a longer run and don't set this heater code

 

So the only reason to use 13111s is if you have LTs and need more wire for the O2s? Are they more acturate too?

 

It's not that they are more accurate, normally. It's
that they remain accurate, under conditions where
the stock ones will be asleep at the wheel. It's all
about the heater wattage, making up for the heat
lost to the greater surface area of the header type
exhaust.

If you just have stock logs then they have no additional
value over stock sensors. Unless maybe you live in
north Manitoba or something.

 

I have had em in for a couple of days and so far I am liking them
Thanks Jimmyblue ,TAQuickness and Horist
