I need to replace the Lambda Sensor on my 95WRX. I know the original one is in the drivers side header, I doubt it will come out easily . There is a bung in my downpipe and I am pretty sure I have read on here that it is a better place for the Lambda but I cant find the thread that I thought said that .

Can anyone confirm that I can put the new Lambda in the downpipe and that it will read correctly - I am sure the wires will reach and if not I can always extend the loom!

just about to change mine on my 93 wrx as overfuelling and would be lot easier to put in downpipe instead on manifold so be interested in what people in the know advise.

 

it will fit and be fine 97/98s upwards had it there as standard

 

+1 yep downpipes fine

 

As people have said, i have had a couple fail in the headers due to the pressure's there,
A mapper told me that the downpipe is a better place for it.

 

Yep as above always had fitted to DP and never a problem.

 

That's great news - hopefully the bung will come out easliy
