BMW's cold air intake is already the best intake you can have. You might get better airflow by changing the air filter and thats about it. All the aftermarket claims are sucking hot air. It all results the same formula but with alot more behind the scene drama. Car sucks hot air ecu/sensors compensate, all resulting the same air/fuel mixture.
Unless you have a tune then you can adjust some settings
Anyways...who cares, it looks good and sounds good, enjoy it
