hey nate... we'll like everyone said.. u need three hoses.. but u basically can use the old hoses cuz the hose really won't make a difference.. because i have an Injen and like the hoses are the same.. except for the little injen logo on the hoses.. and well don't worry at least u didn't get jipped that bad.. u might jes need to drill a small hole.. at least they gave u that rectangular box cut for u.. otherwise u got ripped off.. but yeah.. if u wanna see how the injen looks.. on the car.. i got this pic off this car site.. which prolly got it off injen...

like u jes need to take out the stock intake and like all the hoses will basically go to the same places.. good luck..
