Help on air filter

[nicespy]

I want to buy a K&N airfilter for my 2012 fiat 500 sport 1.4
I found two different numbers that say they are the one I need
K&N 33-2487 and K&N 33-2471
I bought the car , live and drive in the USA I do not know if this matters.
Could someone please give the right number please
Thanks Ed
