Yes you just need the complete manifold ( manifold, small disa, large disa, 6pack of gaskets). Disassemble the used manifold and wash with soap, take your time.

As far as if you need it, well look at the German tuned 128i non disa dyno that I liked to above. Compared to the 125i or 130i they are missing the pumps and valleys in the hp and tq curve. Mid range power certainly benefits with the manifold.
