Hi all
hope this is,nt a stupid question but what are the two pipes attatched to the air filter lower housing for they have a blue sensor type thing on the end.The reason i ask is one of the pipes on the drivers side has broken where its attached to the engine . Will this effect the running of the car? Its a 928 s4 1987 manual trans by the way.

cheers Grahame

Do not fret they go to exhaust manifold they are for exhaust gas testing co you can blank off if they make puffing sound nine do not just left broken rusty pipe.

Thanks for that Potdog .i was thinking of making a sleeve to join the pipe up again but if it does nothing i may not bother .
thanks Grahame
