Anyone know where I can find 02 extension kit? Just installed ARH Longtubes and stock 02 sensors do not reach.
Tried searching with no luck.

You do not need to extend the O2 sensors. Just look closely at the O2 wiring that goes around the transmission on the driver side. Pull the wiring out of the metal clips that hold it in place and it will reach. Also make sure you install some 90 degree O2 foulers for the rear sensors. The only thing you need to extend is the wiring for the oil level sensor.
Hope this help.

Hi Vioilio, I tried that and it still seems that it is about 3 inches too short. Or am I missing something here?

Here is a picture for you:



As you can see , if you use 90 degree O2 foulers and get the oil sensor harness extended you will be able to connect to the main O2 wires.

Thanks Vioilio.
This helped, I tried and all is settled. Appreciate it.

Did you have issues with the drivers side header rubbing? I read some reviews that a few people had this issue.

I read that too but ARH assured me that it is taken care of. I still did not drive the car, I am waiting on a few parts. I will be sure to keep you posted if you'd like.

I hate to drag this ancient thread back to the top, but I'm having a terrible time tracking-down an extension cable for the oil level sensor.

A buddy brought me his E55 to sort-out after he had a meth-head install headers for him. The O2 sensors aren't even installed! That could be why the check-engine light is on why STAR can't get any data from the sensors <rolling eyes>.

As the earlier posts suggest, I'm pretty sure I can move the harness enough to plug-in the new O2 sensors, but I will no longer be able to reach the oil level sensor.
Someone please point me in the direction of an extension cable for a 2005 E55 with headers

I just stumbled on this post

I may simply splice-in some more wire inline if folks agree that it shouldn't hurt anything

Thanks
