JLT intake = Cheaper, $155 on mustangtuning.com, one of the best intakes for performance and has a 4inch tube. However it looks like an intake i could build myself at home depot and it looks like crappy quality, but i have never seen one in person.
K&N = your safest bet, around $175, good performance, but dont listen to the dyno tests on there website because its tested on a 1999 PI mustang not an SN95. Has good looks, i only wish they came with orange reducers like in the photos. I just yesterday installed one on a 96 chevy tahoe. I like K&N because they shape the intake for best air flow.
C&L = This is an okay intake, however some mustang magazine had a project car (96 mustang gt) called red headed stepchild or something and they said that it only gave them about 3 rwhp and thats with a MAF kit from C&L also. Another thing to consider would be that the metal tube could be louder and become heat up the air.
MAC = I'v not herd much about this, looks like its all for show to me.
OR: untill your ride needs more air, just pop in a K&N filter and take off the air silencer
