I want to purchase a Neuspeed P-Flo for my GTi, i am aware that some other induction kits come with a partition that sections off the filter from the engine bay so it is provided with fresh cold air, i know the P-flo doesnt come with anything like this so i was wonder if their is a universal option or something i could make to do the same job or is it not necessary? Alternatively should i just run a duct to the filter from the grill?
