What does 1.8L I4 MFI / MPI when referring to an engine?

I'm looking at a 2004 Pontiac Vibe and it has a 1.8L I4 MFI / MPI engine. I understand the 1.8 L part... Could someone explain the rest to me?

    I4 = inline 4 cylinder (basically 4 cyliner)

    MFI/MPI = multiport fuel injection (basically ALL cars are MFI now).

    Basically it is a 1.8 liter 4 cylinder engine (doesn't sound so exotic any more, huh?)

    :-)

    Good Luck..
