hi ive seen a nice 55plate e46 330d for sale ive asked him if swirl flaps been removed this was his reply is his info right or has he been misinformed thanks simon.
his reply is below,
The Swirl flaps are still in it has the plastic type same as the E90 shape.
BMW changed them 3 or 4 times during the E46 range as this is one of the last e46s it has the final type. A bmw specialist said it's only the metal ones you need to worry about and don't worry about them when I asked to get them taken out. Also had the same opinion from a mechanic mate of mine.
