Please advise why you blank of the swirl flaps and not just remove the butterfly and leave the rest of the construction as is.
I drive a e90 330D and removed the intake today just to find that mine was still ok, but while I am there I wanted to remove them - but noticed I bought the 22mm instead of the 32mm plates, there with the question- why not just remove the buttery on each cylinder
