147 uses a different intake pipe but the same airbox as the later 156 and GT. Pipe is completely different shape and looks much shorter than 156 pipe.
Parts and prices below for this interested.

Updated this posting to include the V6 and TS intakes for comparison:
1) the 147
GTA intake system
2) the V6 intake pipe is the 2.5 V6 version not the GTA as eper doesn't distinguish in the picture, just the part numbers
3) that long intake on the TS is for eastern european countries, obviously where the noise emissions are far less strict: £35 from dealer!! £44 for original TS resonator unit ...
