so i would like to install a cool air intake on my '93 4.9L, and i am wondering what the best way is to do it since i have the intake setup w/ the 2 tubes coming from the airbox and going to the throttle body. do i just buy 2 filters or what? btw i am going for a setup simular to this https://www.f150online.com/galleries...5583&anum=1474
not blowing $200 on a K&N.
thanx.
