HP and performance for a V6
 

Hey, I was wanting to add as much HP to my car as much as I could without spending a lot of money on superchargers and such. I've got a 96 V6 mustang with duel exhaust. I have a cold air induction system from UPR Products but it doesn't seem to be the right one. Other than all of that and underdrive pulleys, what can I do to add more HP to my car and allow my car to run better without spending a lot of money on performance parts? Thanks.
