2009 4.0 ltr V6 , 45th anniversary addition
I have been having my Mustang for about a year now and have decided to start making some mods, so I have come to you good people for some good ideas on where to start.

 

Welcome to TMS and thanks for sharing a photo of your "09" 4.0 V6. As for mods are concerned, I'd recommend starting out by getting yourself a Ford Performance air intake kit with Ford Performance flash tool from Steeda Autosports. They're considered as one of the top Mustang tuners in the industry and have 30 years of experience to back it up. If interested? I've provided a link with Steeda's website including the Ford air intake kit with flash tool for your 2009 4.0 V6. You can also contact Steeda with any questions/concerns that you may have as well.
