    hey all,

    quick question - is there any difference between a TT plenum and an NA plenum?

    Thanks,

    exaclty the same..

    only difference is between 89-93 and 94+ plenums . and 96+ are j30 plenums
    na and tt are identical

    TT plenum has an extra port drilled on the left hand side for the recirc valve.

    Both have the port, but the NA on has a blanking plug in it instead of a plug with a line in it.

    Cheers
