    the ribbon is a government mandated flame arrestor in the event of a engine back fire. keep in mind that your intercooler also acts as a flame arrestor.

    so let’s be realistic. Ever hear your modern fuel injected engine backfire? I haven’t, and have never heard of it even happening. And if it did, do you honestly think the back fire flame would travel through the intercooler and into and out of the air intake? No way!!

    Regarding “voiding warranty”
    They cannot “void” your entire skis warranty for doing a mod to your ski.

    They can “deny coverage” on a failed item if the modification is proven to have caused the failure, but your entire skis warranty is not VOID!!


    For example, let’s say you reflash your ecu with a performance tune. If your steering breaks, instrument cluster goes bad, a sensor goes bad, etc, then the reflash could not have caused one of those items to fail so they cannot deny coverage.


    Now, if you have some sort of engine failure then they could absolutely deny coverage on the motor repair.


    Point i’m trying to make, is your entire skis warranty is not VOID if you mod your ski. Research Magnusson Moss Warranty Act. It protects us consumers when modding our skis ��

    Greg installed a Riva intake manifold upgrade and Riva power filter on a friends ski last night. This was a bone stock ski and the ribbon was dislodged and pushed through into the intake manifold with minimal pressure.

    This is really disappointing! Ugh. I really didn’t want to have to do this…such a huge PIA. Not looking forward to it.
