Hello georges 928s,
In the picture below, is the hole you are referring to in the location pointed at by the green arrow? If so, there should not be an open hole there. Mine has a black plastic plug as you can see from the picture below.

yeah, a hole in the spider would represent unmetered air in the intake. That would not be good for your air/fuel ratio.
when you get a chance, get your cars info in your signature. It will help people answer your questions.

Common question about the above hole. Only used in the CIS cars to hold down the intake over the air plate. Nothing to worry about.

That hole is only for the cis fueled cars, the hole is cast completely through the intake mani and there is no "Hole" per se. It is threaded if you don't like it just thread a bolt into it for peace of mind!
