I just bought an 03 Cobra Vert w/36k miles. Only mods i'm aware of are the magna flow exhaust. I purchased an ext warranty from ford for addtl. 4yrs/48k miles. Want to do more modifiications, but not sure what is worth the cost and what will not void the warranty. Recently purchased a JLT Cold Air Intake, but havent installed it yet. Any Suggestions?

Thank You,

Stu
