E46 for sure.

E90 swirl issue is ramped right up imho.


I see someone had sw actuator problem above. Surely the actuator not working properly isn't quite the same as terminal ingestion?
Agreed! with my experience I've not seen anything about the later flaps on e90 6 pots at all, the swirl flaps on the later e90's play a larger part with the ecu software (swirl and tumble), my own 330d is high mileage and they are still installed and I looked at them last year when I removed them to installed pwr blanks after reading all the horror stories, I then ran the car for 4 weeks and noticed less responce at low revs and a bit more pedal so reinstalled them and found it ran much better.
I think the best way on the later engines would be to remove them along with the dpf and have remap
