yes i agree. na ea82 mpfi xts are pleantyfull

if its mpfi it says multi point fuel injection and has two aluminum runner s on each side, instead of just one tube.
if its spfi it has a tube, and yours could even be a leftover carb, which has a wierd almost oval shaped aircleaner on top.

FYI, in '85 they actually made a few GL-10 sedans and wagons with MPFI.

I have one, it's a '85 GL-10 2WD wagon with MPFI and no turbo. It's the only one I've seen other than XT's.

The intake plentum should say SPFI or MPFI in large letters ontop.

Either that, or look at your engine block. If you have metal tubes leading to Injectors, 2 on each head... then you have MPFI. If there are no injectors in the heads its a SPFI or Carb.

my intake plenum on my 88 gl wagon just says "Subaru F.I." it's single port but like i said, it doesn't say spfi or mpfi on the plenum. is everyone else's the same, or is my car just that unique?
