335D - Do air scoops do any good?
New lucky owner of 2011 335D here.
Since diesel relies on air to create combustion inside the engine, would that mean that air scoops should create a fairly dramatic increase in car power? I've transfered my old MDF scoops from my ex 325i and haven't driven the car yet due to quite nasty weather. But some knowledgeable feedback would be great.
