Default Denso O2 sensor for LT headers part number

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.

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.

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

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.

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