there will be fittings for lines, as many as required, eg vacuum lines for fuel pressure regulator, boost controllers, wastegates etc. they are airline fittings that will most probably be located at the rear of the plenum and out of sighted, keeping the engine bay clean.
i would recommend the use of at least a chipped computer or something similar to a piggyback system or stand alone as the ultimate (if your budget allows).
there are no places to fit the aac/ficd.
these are the sacrifices that need to be made to take full advantage of the plenum.
sorry if this puts people off, but adding the facilities to have these standard components added would detract from the full benefits received from installing the plenum (it would also not make it look as good, something that needs to be considered).
anyway, do these components still work on your car ? as i have found that many, due to their age, no longer operate as per standard and have no real affect on the car's performance. please correct me if i am wrong.
