K&n has this listed as 50 state legal. carb compliant. but amazon will not let it be shipped to my location in california, what gives?

Its compliant but not registered and approved by Commifornia. It's a long approval process so it's not worth k&n's time.

does the electrinis attach or plug in i think th mass air flow sensor

It plugs in. Just follow the instructions in the package.

Do you need to purchas a throttle body spacer for a 2014 ford stx 5.0?

My F-150 is a 2013 5.O. The K&N set up fit perfectly without any spacer. Do not know about the 2014.

Does anyone know the size of the dry charger wrap for this filter is?

That should be available on the K&N website. Give it a shot.
