How to optimize your BWM's engine for better performance?

My BWM's engine seems to be running slow lately. How can I improve its performance?

Firstly, make sure to regularly check and replace your air filter. A clogged air filter can greatly reduce the air flow to your engine, causing it to run slower. This can also negatively impact your fuel efficiency.

Another important aspect is to regularly change your oil and use high quality oil. Old and dirty oil can cause friction in your engine, which can lead to poor performance.

One thing that most people overlook is the spark plugs. Make sure to clean or replace them every 30,000 miles. These small components play a crucial role in the performance of your engine.
