I recently bought an E82 125i. I know that a common mod they do on these cars is to install the 3 stage intake manifold from the x30i models.

Can anyone confirm if my car has the 3 stage intake manifold? It looks like a DISA valve on the inside maybe?

Any reliable tune to install to increase the power?

I also noticed some holes. Please check the last 2 photos. No idea what was there. Also wasn't there supposed to be the power steering reservoir near that place?

Any help/info is much appreciated.

Thanks
