Hi,<br><br>
<br><br>
I've heard that a mercedes 1.4 bar coolant cap is the best solution for my car (1990 BMW M3).<br><br>
It was made by the same manufacturer that made the BMW one, but is supposed to be better.<br><br>
Does anyone have any information about where I can get one of these?<br><br>
and maybe a part number... <br><br>
<br><br>
Thanks,<br><br>
Han.
