Saw a million requests for this but no answers. The Denso part number for the Vette rear O2 sensors (Use as fronts in an F-Body with LT headers) is 234-4617 These have a 44" wire on them.

Now I can get the correct ones. The 234-4025 are too short for LT headers.

 

HAHAHAHA (Not laughing at you btw)

I remember that thread.....

 

I bought 2 new ones last month for a new dyno tune and the ones listed for our cars @ Oriley, Advance, and Autozone were the factory 02 zo6 sensors with the long wires.

 

Here's a picture of the two. The 234-4025 on top and the 234-4617 on the bottom.

 

did you order them already? if not then keep looking for the cheapest. they can be bought for around 30$. dont jump on the first link you see. am going with denso too, my O2s are busted.

 

If you look on Rockauto.com they list the wire length for all the Denso O2 sensors.

 

I have both of them here, probably going to install Tuesday.

Jontall - I was not able to find that into on rockauto.

 

i dont see why you would need extra long wire with longtubes i have hooker lt and the harness is 8 inches away from where the sensor goes in the collector,any advice would be appreciated.

 

I have the Dynatech headers. The 234-4025 sensors are too short, by about 4"-5" The extra long wires are far easier to zip tie well out of harm's way. Not needing an extension harness of questionable quality is an added bonus.

 

F body with ls1 not lt1.....let's just clear this up for the guys like me trying to find a sensor for my lt1 car.

 

This was a 2.5 year old thread resting peacefully and not likely to confuse anybody till you dug it up.
