X1 Hood Sound Insulation
Anyone interrested to get the underhood sound insulation?
All our X1 doesn't come original with the car.
I guess BMW didn't think it is needed.
But since the 2.8xdrive was introduce, I think the sound insulation should cut at least 15 to 20% of the timing chain noise.
I found that it is possible to get it thru BMW.
