how hard would it be to put on an BMW X3 3.0 6 cylinder?

Just wondering cause i might be selling it.

 

you have to take it off the comptech bracket and make a bracket that would fit the X3, which would probably be very hard. you'd have to make piping to go from the outlet to the X3's throttle body which should be easy. but you might also have to upgrade the fuel pump, injectors, and FPR for the X3.
