I think there is also a difference with the side intakes behind the doors, they're partly covered in mesh which I believe isn't on the V6 intakes and there may also be a difference with the structure within them. Not really a major differentiator but more something that you could spot if you know to look for it but probably wouldn't even realise if you didn't.You can’t see the engine on the I4 they have a full black cover on itbtw are there any external/internal differences between the i4 and v6? Ie visual differences? Or is it literally just the engine and trans that are different?
