Nope, it's for length, period. They install the motor, fill it up with what FORD says it gets,
then they twist it till it reads full. IF they're pre-made twisted, then your THEORY may

how's your hood btw? I also have an 06 Gt, did it start peeling yet?

 

I have an '08, the OP has an '05, but mine hasn't done anything yet.
