How to increase the performance of a BMW 4 Series?

I have been experiencing lower performance with my BMW 4 Series lately. Are there any specific maintenance steps or upgrades that I can do to improve its performance?

First, make sure to regularly maintain your car by following the recommended service schedule. Additionally, consider upgrading your air intake system for better airflow and performance. Lastly, using premium fuel and keeping your tires properly inflated can also improve your car's performance.

Installing a performance chip can also significantly increase your car's horsepower and torque. You can also optimize your car's exhaust system for better performance. And don't forget to check your spark plugs and ensure they are in good condition.
