I would check for operation first, I think they are either connected or not. Mine were snapped and need replacing hence me buying new ones.

What's the reason to clean the inter-cooler? is it very dirty or has lots of oil residue in it?

My advice to clean and fix or improve what you have before thinking about spending big on brand new manifolds. Just make sure everything functions as they are meant to.

You are talking totally different thing here, diesel manifolds are nothing like petrol, just for start petrol have 1 and diesel have 2 separate one for each bank and the function and operation of flaps is different as well.
