Just giving my cousin a hand fitting a stainless protech exhaust manifold to his corsa sport, but i've notice it has lambda bosses on just the primaries.
So it will be monitoring oxygen from just one cylinder, quite stupid if that cylinder decides to run rich/lean for some reason, and the ecu adjusts the whole engine.

Have people just fitted there lambda into the std boss? Or had a lambda boss welded into the collector where it can monitor all 4 cylinders?

Ok mate, i'll put it there for now.
Should get it sorted asap tho, no doubt the lambda probe will be obstructing gas flow slightly too.

Good point mate, never thought of it like that. As for mine, I just put it in the 1st hole at the top and never had a problem.
