2014 V6 Performance
So I recently traded in my old Mustang for a new one. Nothing majorly fancy, just the V6 premium with the performance pack, and some luxury features.
But anyways, I'm wondering what are some really nice bang-for-your-buck performance upgrades that will, or won't void the warranty.
I already know that the K&N Air Intake is a great start without voiding the warranty.
But I'm kind of curious as to what else you can add on to the 3.7 that gives it more guts, and actually supports the 3.7L engine.
