    They have replaced it with the XX and the XXX SCers. So they have discontinued the 1st gen 137mm I believe. You may find one for sale here and there. They were on a close out sale of like $450. So alot of guys bought them.

    The first riva x charger upgrade replaced the front housing bro. This or the spacer basically are the same thing.

    NO the XX is a superior SCer then the Original Riva 137mm X upgrade.
    The one he has only needs 48to 50lb injecters
    the new XX needs a FPR.

    I would install and check A/F
