[rgorm2500]

what do i need to soup up my intake setup for my kfx 400. i got the UM airbox, and need to know what else to buy to make it work. i found out that the 250r filter is bigger and flows more air than the stock one. which intake boot for the EX do i order?

you will need an intake boot.
you will have to modd it some ,but dont cut the small end off .
if your worried about what year to get ,dont ,seams to me there all the same.
