How to Increase the Power of a BMW Engine?

I recently purchased a BMW and I'm looking for ways to increase its power. Are there any modifications or upgrades that I can make to the engine to achieve this? I'm not looking to completely overhaul the engine, just simple modifications. Any advice would be greatly appreciated. Thank you!

You can start by upgrading your air intake system. This will allow for more air to flow into the engine, resulting in increased power. Additionally, consider upgrading your exhaust system to allow for better exhaust flow.

Another option is to install a performance chip. This will optimize your engine's performance and can increase power output by up to 10%. Just make sure to do your research and choose a reputable brand.

If you're willing to spend more, you can also consider installing a supercharger or turbocharger. These will significantly increase your engine's power but will also come at a higher cost.
