FUN FACT: there is documentation on the web about people who have spent about $200 for a used OEM three stage intake manifold from an "si," bolted it on and converted their 3.0i into a 3.0si using strictly BMW parts. Due to the interchangeabilty of parts from those specific year models, there is a loophole in the design where you can actually pull an "si" intake manifold off a 3.0si model and direct install it to a 3.0 and add about 50hp to the crank which turns out to be around 39hp to the wheels. All you have to do is order the part from a junkyard or similar and then take your Bimmer to a tuning shop where they will "tune" the motor to take full advantage of the new manifold, and the crazy part is you are using only BMW parts! Just food for thought. The 3.0 is sufficient, but I've been thinking about doing the upgrade once I'm paid off. I can think of a lot worse ways to spend an extra $200-300
