Im looking for some advice on what to do first to gain the most hp.Im sure you all hear this time after time,but If you could give me an opinion of what bolt on mods should be done first,I would appreciate it alot.Ive seen the 75mm tb and plenum,cold air intake, Are those great first mods or what??? B.T.W Great site... Thanks..Brian........................

 

welcome, there's a 4.6l specific setion where you would certainly learn a lot. i think the first mods to our stangs should be your choice of 3.73 or 4.10 gears, exhaust and midpipe
