Hey guys,
I own a 2015 M4 and I was thinking about increasing the performance of the engine with either a downpipe and JB4 tune or get a Meisterschaft complete exhaust and a aFe Cold air intake.
The only thing that scares me is the Maintenance Plan getting waived due to these changes to the car. Does this differ from each BMW dealer or once there are changes I would have to pay for the Service and so on out of my own pocket?
Has anyone else gone through the same problems? Any solutions?
Thanks!
