O2 OXYGEN SENSOR BUNG with Headers

Where does it go with long headers?

Stoke manifold is a no brainer...

Im looking at 3 places.. end of header,,, In the reducer? or the pipe itself..

Pic would be great....

Thanks

 

Collector b4 the flange...you can go in the reducer after the flange if need be due to coated headers

 

That was my Number 1 thought..

 

I put mine in the reducer.Didn't want mess up the MT's. Would do it that way with any header though.

I noticed reducers with bung for sale at Jegs, summit ETC...

 

Closer to the engine is best from what I've read but of course the collector makes the most sense. Also it needs to be in the upper part of the tube so the sensor points downhill, keeps moisture off it...
