hi does anyone have a version 4/5 as iv bought a 1998 sti and it has a hks ssq bv which im not too keen on,i have the standard one but im struggling to fit it,ie how it goes as i have the top hose from intercooler to top of the recirc and bottem hose to pipe below that was blanked off for the hks,iv tried to fit it but still makes whooshing noise when changing gear,any help would be great,its the plastic L shaped recirc valve not the metal bolt to intercooler type
