i apologize i should have been more clear. im talking about the hose from the air box to the turbo. i am currently working on getting a new air cleaner box and would like a different hose to help smooth out air flow. i already have a tag which seems to help and will probably go to a tag 3 when i get these other parts im trying to get more air flow to cool the egts a little and i think these parts will do it. i just cant find the cool blue hose for 2nd gens only 3rd gens
