intake mods

i was curious, what is a fair price to pay for a short ram intake? any recommendations on where to purchase, what to purchase?

i don't want a cold air, because i live in snow country and don't want to suck in water. i'm not much of a car guy, so 3 hp won't matter to me.

any recommendations?

i've been thinking about the dc sports dac. here's why:

i hear they are good (but i come from a motorcycle background and i understand that companies can get great reps by over charging and spreadig their own rumors or living off yesterday's success)

i want a reusable filter

i like loud cars

and i don't want to have to rip it out in two years because it's crapped up.

what about those cheap ones on ebay? i don't think i want to go cheap, but it's just a tube more less anyway, right?

last question, anyone ever try a spacer plate on the throttle body. back in the day, i had a friend with an escort and he made a spacer plate for it (about an inch) and it ran pretty good with it (for an escort). i was curious with all that honda puts into their cars, can anything be gained by adding one.
