I've got the new 02 Expy. 4.6 triton v8... love the truck but i want to pep it up, its quick allready and sounds nice but i'd like to do some performance mods.. whats a good way to get started?... i was looking at K&N Air Filters just to start... not much but something... are they worth it?... what esle can i do for around 50 or 100 bucks a mod ? .. i want to start with a few small mods here and there and see how it works out before i start dropping some coin on things like a chip or exhaust.
thanks in advance for the input.
