04_GT

Hey everyone, I'm new here and to mustangs. just got an 04 GT and I'm seeking advice on bolt on mods that wont affect my warranty. I'm looking for the biggest bang for the buck, I'm thinking that a cold air intake is a smart bet but which one is the best for the money??

anyone have any suggestions that meet the above criteria please speak up.

thanks,

id go with an underdrive pulley set. cheap and easy to install. id get magna flow mufflers. a cold air intake is good, but it would be better if you also got a larger MAF sensor
