-You got an AFE so that won't help much honestly because you have a NA engine, what you should have done was gotten a Euro Box intake for N52 or did a simple K&N filter drop in.
-Air scoops
-After all the performance mods you should get an AA tune to tie it all together
-Also knock some weight off your car
-Tires + wheels
-Coilovers, don't get springs because stock shocks won't hold it up too long.
-Sway bars, strut bars, etc.
That's almost all you can do to these cars, not much you can do that doesn't require lots of $. Now if you had a 335 those become monsters after a few modding.

THIS
plus ditch the run flats... you will save 10-13lbs from each wheel. If you dont get a muffler just delete it as a whole....... that will save 35lb. and with the 2nd cats + resonator its not bad, exhaust note wise/sound.
theres a thread here where a guy made is US airbox into a Euro box... basically you put a cone type filter in instead of the flat one that the US uses.
last, the 3 stage intake manifold from a 2006 330i of 530i.
The manifold, AA tune, headers are the big power gains... 10-15rwhp each.
the intake, muffler are prolly 4-7rwhp gains. the scoups only help once your doing 60mph +
