I'm wondering, because i don't know' about cold air intake, what kind of increase in fuel millage. I know it increases HP, but what kind of increase in fuel millage that i hear about. I have a '99 F-150 4.6 4x4 - ext cab, XLT. I'm going to be pulling a 28' trailor this summer for camping and wondering if it would make enough differance to consider the cold air intake.

 

I don't think it would be that much but every little bit does help.

 

i think they advertise like 1mpg?

but for the times you'll be mashing it to hear the cool woosh sound, your gas mileage will probalby go down

i love my AF1 though!

*edit* wow! i just realized how old this thread is. LoL!
