I wish we could help but we do not have any CAI's for the Mustang yet. BTW, you are posting in the right spot, this section is specifically for other vehicles such as the Mustang. Although we don't currently have a CAI for your vehicle, if you can fill out the following form we can get in touch once it goes into development:

Thanks and good luck in your search!
