I come from the motorcycle world, so I've never heard of a heat sink before. Any idea on the price or part number?

Heat sink: 11617584527
http://store.bmw-mini-mania.com/part/11617584527 $200
Heast sink gaskets:11617584528 you need 2
http://store.bmw-mini-mania.com/part/11617584528 2x50=$100
depending on the manifold condition,you may need to chnage these gaskets at the connection of manifold to engine:11617547242
I didnt because mine looked okay, and its just air
Honestly I would get 11617559523 the regular disa manifold and buy an air intake upgrade for the $300 of extra cost, or even a tune from AA, Eruocharged,OE tuning etc

Any idea where the hp disparity between the #25 engines and the #23 ones lies? I'd hate to do the entire swap only to end up with just +10hp.

128i stock is ##24 manifold = 230hp
most cars with disa manfifold #23 = 255-265hp stock power ( true for MSV80 ecu/dme found in 2008+ cars)
##25 manifold is same engine, choked by software to offer low tq increase & less hp ( just look up any review on 2011 3.0 X3 with n52 vs the 2009-2010 3.0 X3
