Hi,

I‘m trying to find out as much I can about separate inlet- and exhaust-manifolds for my B30A.It is now equipped with a so called ”Siamese manifold combination” and I would like to change it to a setup where the manifolds don’t touch each other. (to prevent heating up the intake).

What models / years are the separate manifolds used?
Or was it related to sales markets?
Are there other parts that need to be changed when swapping from one setup to the other?


Thanks,
wouter
