Hi guys this is my first time on here, I have a question and hope someone out there can help. I have a 320d 2008 with n47 engine, the inlet manifold has exploded and I'm trying to find a replacement, I'm only coming across manifolds that have no swirl flaps and am woundering if this can be used instead of the original that was fitted to the car, which has the swirl flaps. The manifolds look the same but obviously one has no swirl flaps. Part numbers are very similar too 11618507240 without flaps and 11618507239 with flaps. I've read that people have blanked of swirl flap manifolds in the past and was thinking I could use the non swirl flap one instead. Is this possible.
