Question Any mods for an N52 port injected 2.5?

I read up a while ago and a 3 stage intake is not available as it is a 2.5 port injected engine.

Beautifully smooth engine... very technologically advanced. Probably more advanced than the N53 onwards...

Wondering if there are any upgrades out of interest.

Dinan Ram Air kit, ECU Tune, catless headers/exhaust, muffler delete, M3 suspension parts, coilovers, light weight wheels.

Just a couple performance and handling mods off the top of my head.

Are you sure you don't have 3 stage IM? I have an euro 2.5l N52 and it has 3 stage. I thought I had only 2 stage but then I decided to look closely and yes there were 2 disa actuators so it is a 3 stage.
