I don't see where the PVC would not work ~~~~~ I thought about doing the same thing, but went ahead with the OEM Kubota high mount, and love it. Kubota's kit installs perfect, and don't get in the way & also, don't have to worry about the water thing at all . I just checked my filters yesterday, and it's just as clean as the day I installed it. I like the air-box high like that >>>> My idea where you are talking about doing the pvc, I was thinking more on the terms of a flex big hose, like the one coming out of the intake of the engine >>>>>>>>> [Y]</P>
