RE: Free
If you still have your stock air box, one FREE thing you can do to your Mustang to gain some "pep" is to remove the air intake silencer. This is located on the passenger side of the engine compartment. It is a rubber molded piece that extends off the plastic air filter housing. It extends into the fender well about 7" or so.
1.) First un-latch the air filter assembly, 2 latches on the 3.8L V6.
2.) Unscrew the bolt that holds the air filter in place. There is only one bolt. Use a socket set & wrench.
3.) Lift out the entire plastic air filter assembly. The assembly is held in place at the bottom with 2 large rubber grommets. On the 3.8L there is a plastic tab at the bottom of the assembly that holds it to the MAS Air assembly, lift up and out, not forward. Lifting it straight up was easiest for me. The rubber intake hose can bend slightly to accommodate this procedure. Make sure you don't cut or pull loose any MAS Air sensor wires when doing this.
4.) Separate the "rubber" intake silencer from the "plastic" air filter housing. Just pull it loose.
By removing the air silencer you more than double the size of the outer intake port on your Mustang. With this thing in place, it's like trying to breathe through a straw.
5.) Re-assemble the air filter cover. Re-secure the air filter to the MAS air assembly, insure a proper seal, don't force anything . Drop the air filter housing back down, securing the two large rubber grommets at the bottom of the air filter housing. Re- latch the air filter housing to the MAS air assembly. Re-bolt it back in place (single bolt at the top) .
6.) Wash your hands, then drive ! Oh.. keep the air silencer handy. In the future you may put it back as part of a "ram air" system or whatever.
After your finished, you will be able to see the conical shaped air filter element slightly (if you lean over and look). For the most part, the air filter is still enclosed but with a much larger opening
While you have your intake apart, you can use some aluminum polish on your throttle body inner lip before the butterfly valve and polish the shizz out of it untill it's really smooth. You'll get a quicker throttle response from these two things.
edit: also get a K&N replacement filter as soon as you can afford one, it will breath even better. They're around 40 bux.

RE: Free
also there is a mesh screen that is in there. take your air filter box off and look down the air intake tube and right at the beginning of the tube is the mesh screen take that off. it wont hurt anything. that is just another thing that restricts air flow into the motor, it wont make a very big difference but every little bit helps.
