Sorry to ask such a n00bie question, but I can't find this anywhere in the FAQ or on any third gen websites.

Dear friends,

I've just installed a set of hedman shorty headers in my 87 TPI 5.0 IROC Z/28. I am very pleased with the install, only had to take 1 engine mount loose and jack the engine up 1/2 inch to get the drivers side on.

My question is.. The stock exhaust manifold (driver's side) had a sensor (i THINK it is the O2 sensor) -- (i assume to feed info to the A.I.R system which is long since removed from my non-street legal race car). I believe that I do NOT need that sensor in my header, though I have a screw in bung welded in there (capped now) all ready to go in should I need it.

thoughts? Is this the 02 Sensor and is it required? or only for A.I.R??

its needed make sure you put it back in o2 basically tells the computer what to do

Or, to put it another way:

It is needed. Make sure you install it in your new headers. It is needed for the ECM to make mixture control decisions.

It doesn't have anything to do directly with A.I.R.

I just pulled it out of the exhaust manifold, AFS 16P is the part number. I assume that it's better to just put a NEW one in instead of re-using the old one.

I'll pick one up and go with the new.

thanks guys,

brian

I just want to report back to the group that I was able to tap and drill out the bung-hole with a 7/16 hole and insert the new O2 sensor in the header tonight. Those tips of using a 7/8 inch wrench were RIGHT on, worked like a champ.

So, I am hooking up the Y-pipe and Magnaflow tomorrow and thursday and heading to the races on Saturday.

THANKS EVERYBODY!
