Morning all;
Just red this thread. I recently removed mine on my 330d. I will not recommend it thou. These are multi valve engines and you will notice that the intake has 12 outlets, 2.0d's has 8. The reason for this is for better lowdown torque. This is where the swirl flaps come in. On low rpm it is closed, so the engine runs on one intake valve per silinder, creating more torque. Above 2 000 rpm the swirl flaps start to open. Thus getting optimum power,smoothness and fuel consumption. By removing the swirl flaps, one reduces the lowdown torque which makes the car using more fuel as you have to accelerate harder to get the same power and using more fuel. A better thing to do is to blank the EGR and stop putting back diesel fumes and carbon into your manifold and engine. It's just my opinion, everyone do as they please.
Have a great day and weekend.
Ps, the reason I removed mine, was to try and sort a rough idle on my car, which was unsuccessful by the way.
