Hi
I’m investigating a rough running issue.
Although it could be a vacuum leak, turning off and restarting the engine tends to cure the problem completely, so I conclude an electrical fault. Plugs are new. This engine (Alpina) uses old style M54 coils.
The problem is that the BMW ones don’t come with the rubber boots, so I would need to reuse the old ones which I’d rather not. The second problem is that Bosch, Hella etc now make these components in China. I’d rather not buy Chinese components if I can avoid it. Finally I have found a Dinan part that claims 10% more power than stock - I have heard that since the company was sold Dinan is not what it was.
What would you do?? Thanks for your advice
