what i did is,i used the cone filter on the stock turbo pipe,the filter goes on the end of the hose that would normally connect to the airbox,then i used the blow off valve in place of the stock airbox IE the space that the airbox connected the hoses,i just stuck the BOV in between where the airbox was.the hose comes from the intercooler to the airbox,mine goes from the intercooler to one side of the BOV,then the other hose goes from the airbox to TB,mine goes from the other end of the BOV to the TB=done
