    RIVA Power Filter install on SHO

    The first thing i noticed upon pulling the stock air box out is how restrictive it was. Have a look at the pics and you can see the tiny intake opening it has.

    An 1800 cc supercharged engine needs to breathe and the Riva Power Filter certainly fits the bill.

    Someone asked me in another thread what was the size of the inlet opening on the supercharger. I measured it at 75 mm.

    Here are some pics of the stock air box in the stock configuration and also after it was removed.

    The Power Filter comes with a threaded clamp on anodized adapter that fits onto the supercharger inlet. Once that's in place then a threaded coupler screws onto that.

    Once the adapters are in place on the supercharger inlet then the roto molded filter tube can be put in place. The filter tube comes with a mount bracket and comes with longer bolts and nuts to replace the two trim bolts I'm pointing to in the pic below. The Riva bolts go thru the trim and thru the power filter mount bracket and then nylon lock nuts hold it all in place.

    Once the filter tube is in place you can install the K&N filter element by reaching up thru the front compartment. You must remove the access panel first.

    Yea, i was shocked at how restrictive the stock filter was.
    I know on the RXP's when we go to a more free flowing air intake we gain 1+ psi in boost.

    I am also in the process of installing a boost gauge on this ski and will post a complete "how to" on how i did it.

    The Power Filter kits will be shipping real soon

    That air kit is a nice install. I like how it goes over the gas tank up high

    Jerry, thank you for measuring the supercharger diameter. Also, are you able to get the riva intake tube only without the K&N filter?

    Hi, On the first picture on the bottom row, is that another air intake hole I see there or is there just one opening. Cheers
