I will ask this group since the so called "Professionals" don't know.
I am interested in purchasing a Cold Air Intake for a 2004 Mustang
with 3.9L v6. I notice that you have one for a Mustang 3.8L V6. Will this one work with my 3.9? If not do you sell one for the 3.9 yet?
In case your interested in mustangtuning.com's answer:
Ford never made a 3.9L V6 mustang
in 2004. The 3.8L V6 kit will fit on your car fine.

Actual mileage will vary with options, driving conditions, driving habits and vehicle's condition. Results reported to EPA indicate that the majority of vehicles with these estimates will achieve between 16 and 22 mpg in the city and between 22 and 30 mpg on the highway.
