How can I improve the performance of my BMW 2 Series engine?

I have noticed that my BMW 2 Series engine seems to be struggling and not performing as well as it used to. What can I do to improve its performance?

Make sure to regularly change your engine oil and filter to keep your engine running smoothly. It's also important to check your air filter, spark plugs, and fuel injectors for any buildup or wear and replace them if necessary.

Consider upgrading to a performance air filter or installing a cold air intake to improve air flow. You can also install a performance exhaust system to increase horsepower and torque.

Try using a higher octane fuel or adding a fuel system cleaner to remove any deposits that may be causing your engine to underperform. You can also get a tune-up to optimize your engine's performance.
