I know on my Z3 the software was a great improvement.

I also put a high flow air filter in because that is what Dinan recommended.
The high flow air filter - is this a cold air intake for the X3? I had a carbon fiber tube with high flow filter on my Z3. Expensive but nice. Or is it a filter that goes into the existing housing?
