Is this N53 B30 intake manifold a 3 stage? I cannot see the 2nd DISA

I purchased what I thought was a cheap 3 stage manifold, assuming a B30 is a 3 stage by nature.

However, I cannot see large 2nd DISA valve usually found above the throttle body, unless I am missing something?



If this is just a single stage, what defines the 3 stage in terms of part number, I thought all B30s had the 3 stage.

Thanks in advance

Looks like a single stage to me. The intake part numbers are:

Single stage: 11617593005

Three stage: 11617593004

The OP is asking about N53 not N52...
