Im thinking of doing some sort of air intake upgrade to my ed and was wondering if i would be able to fit any of the following air intakes and put them straight on without any dramas EF,EL,AU,BA,BF,FG?

no, none will fit unless u change the inlet manifold over to the later ef ef au style bbm (broadband manifold)

all u can do is fit an ea pipe that goes from the throttle body to the airbox as they are larger inside diameter than the eb ed ones and also get an xh ute snorkel (cold air intake).
otherwise u will need to set up a pod filter or something like that.
