Ordered Ventracing’s Donaldson Air Intake

Hi all! Being that I live 40 minutes away from the nearest parts place, could anyone tell me what parts I might need to install my new air intake for my 2011 RZR S 800? Also, I’ve searched but couldn’t find where anyone has connected the Donaldson Air Intake to the between seats std air intake box, if anyone has done this could you privide parts list and an idea how you installed the assy? Carefully read here on using a plate to seal the bottom of the air box and like that idea alot!! Thanks!!
