somthing liek this you mean ??
not very clear buts it an 80mm pipe from the fron bumper sraihgt up the air box , unlikly to give any ram air effect Chris said , youd need one heck of a funnel for that to work so big the drag wouldnt be worth it. does howver give nice cold air , plenum and pipe now feel much cooler after a dirve im prety sure its doing somthing even if theres no gains.
