Air intake diffrences,

What is the diffrence betwen the intakes for the SOHC I-4 DOHC I-4 and the DOHC v-6? I see a whole lot of intakes for the SOHC I-4 the most. and a handful for the DOHC V-6, but i've seen none for the DOHC I-4. is there a size diffrence? or why is these so particular. :banghead:

where did you saw intakes for v6? anyways...the intake manifold is probably different from a i4 dohc to sohc (I'm not an expert with the i4) but i assume it takes a different route or something like that..if they were identical they would have made jsut one for the i4
