o2 sensor and aftermarket headers
Fitting fabspeed headers, their bung hole is by the turbo, my old one inserted by the bellhousing end. How do most guy get around this?
can I just zip tie it outta the way? Tia c |

Are you refering to the OEM o2 sensor for the lambda system?

So you are planning to run without it? If so, you can disconnect it (there is a plug near the engine compartment fuse panel), pull it through the tin and then plug the hole . . .
If not, then I guess I don't understand your question. |

Most people don't use the O2 sensor once they go to aftermarket headers. They set the AFR with a Gunson gas tester, LM1, etc.
Another thing I did was plugged the aftermarket bung and welded in a bung after the turbo. I did this based on the advice of others, but the idea was if any part of the O2 sensor broke free it would go through the turbo destroying it.

Thanx
Does anybody make an extension kit that would allow it's use? Is there a downside to disconnecting it? Sorry for the questions, I'm from the 997tt world. c

thanx!
Looks like I can run without it, no cat or air pump anyway. I may just splice the wires and run it in the FS location, post turbo.

There are extensions to allow you to run it but back it out of the exhaust flow. There are also plans online to fabricate a cheap and easy heat sink from copper or aluminum. Some use the bung to keep the O2 sensor for wideband O2 measurements, etc. I think Innovate might have the parts and plans on their web site.

Thanks to oilonly, I was able to reroute it through another port in the tin, worked like a harm!
