O2 sensor location BC exhaust

[jcb9089]

I have the BC Broncos headers and exhaust. I'm installing EFI and am going to install the 02 sensor bungs.

Does anyone have a picture of where they installed their O2 Bungs?

BC installs the bungs just below the collectors, on the reducers they supply with the headers. just clock them wherever they won't interfere with body, frame, clutch linkage, etc.

Best mounted on the top of the pipe rather than the bottom, so they dont have a chance to collect anything and get plugged up.

I asked the lady on the phone if they would install them in the most common place where they put them, but she said they don't have a common place to put them because every Bronco is different.

I will give it a go on top, close to the collector.

Might be hard to tell but here is a picture before I put the exhaust in. The pipe with 2 bungs is the drivers side.

Thanks, that's what I was looking for.

What is the reasoning for two bungs in one pipe?

The other bung is for an air fuel ratio meter for tuning the EFI.
