    - riva intake
    - riva hull exhaust

    - riva cooling system
    -fizzy intercooler with tial bov ( might need a diff silicon hose to fit the 2019 model)
    - solas impeller and pump kit
    - mapx tuner

    Check whether the 2017 (aluminum intake manifold) ribbon delete kit (IMUK) will fit/work properly in the plastic 2019 intake manifold.

    Try the stock 2019 GP1800R ride plate and intake grate before replacing them. You may like the stock configuration.

    You'll obviously be buying a tune.

    Ribbon delete wont work with the plastic intake manifold. I would run the 2019 ride plate and sell the riva, use the money from the sold riva to have jim cut the 2019 plate for you.

    Will the aluminum intake work on the new models? I'm not a fan of plastic and plan on purchasing one. Does one model run lean on different cylinders like they used to?

    The ribbon delete doesnít work on the 2019 manifold? I ordered it based on the fact that itís in Rivaís 2019 gp1800r section on their website...

    It does not work on 2018 and 2019 GP1800's which have the plastic intake manifold. It is not listed in any of the Riva's 2018-2019 GP1800 performance kits, its only listed separately and they do not specify it doesn't fit 2018 and newer for some reason.

    Riva told me they are developing one for the newer plastic intakes but it is not ready yet. The older R&D ones for the new plastic intakes are still available on ebay for a ridiculous price. I have installed one that I bought from GreenHulk last summer at the normal price of $89. Nice piece but not worth $200 in my opinion.

    Why would you want the alumium intake manifold that is prone to heat soak over the plastic that comes from the factory? It's a better intake manifold all around. doesnt need the brace or the TB adapter. Would be crazy silly to change it.

    I guess it depends on how much boost u want to make...ive seen the sea doo plastid intakes blow apart at high boost. but I haven't heard much on the yamaha...guess time will tell
