    Thunder Products TPI Valve

    jim in Utah

    Not just a gadget......it really works.

    I was kind of disappointed in the size of the vent when it arrived because the description said it was supposed to be 2 5/8". Well, the whole unit is that size but the vent window itself is only slightly bigger than an inch. However, that proved to big enough to make my Kawasaki 700 run great up to 9000 feet elevation. For going above that, two of these units will be needed with that engine size. But this valve worked great and when closed, it lets in absolutely no dust or water. Wide open, the pre-filter worked good enough but you probably won't want to follow anyone too close on a really dusty road.
