i got this info via Air Aid in my email today=Thank you for your inquiry. We are working on the AirAid for the
01' and up Lightning. It should be available in the next few weeks

 

Where can I get one and how much. I would like to see one.

AirAid.com

 

cant wait for them to come out!

 

What is the difference between the 99-00 and 01- ?

 

The 99-00 are rebaged F-150's.

 

i am pretty sure 99/00 had a 80mm mas air sensor and the 01& up have 90 mm ones and i believe the intake ports are bigger in circumfrance on the 01 and up than the 99/00's .i know you don't want mods for 99/00's on a 01 and up.
