There's a lot of good options for cold air intakes with any model Mustang. Try a few searches on the forums and you'll find a ton of threads regarding CAI's and which one is suited "the best."
However, for a '95 v6 Mustang- I'd stick with something like the SR Performance CAI
. The SR CAI is a quality part that keeps a budget in mind. You'll see very similar gains to other top notch CAI companies with the SR CAI, but at almost half the cost.
Hope this helps point you in the right direction!
