I was at the dealership that I purchased my 2006 Mustang GT and dropped by the service department to ask a few questions about Ford Racing aftermarket parts and installation. The service department informed me that they do not install any aftermarket parts even from Ford. Also they told me that any Ford Racing parts are for off-road use only and has no warranty. I love my Mustang but why in the heck don't Ford get with the program list the imports (Nissan, Toyota, etc.) they sell, install, and warranty their performance parts.
