Yeah no need for a big one like that. I got a 6" because I want to swap a 5.4 out of a lightning (into my 2000), but an extended one will not allow you to use your wipers. You'd have to cut it back, and then there is a gaping hole for mother nature to get into. Stick with a bolt on hood and IMO, a max of 3" is enough.
