BMW steering wheel

Hey good people
Q Q
I purchased my 320d and I love it
HOWEVER the only part I wished I could have got from the
sportspac is the steering wheel (didn't love the rest of the stuff)
If I buy the sportpac steering wheel from bmw it will be the price of
a small bond. Can I source it else were, will it affect my motorplan
(I know there may be a problem with the air bag and I don't want to compromise safety) and can I still get bmw to fit it
your thoughts fanatics
