How can I increase the horsepower of my BMW 4 Series?

I recently bought a BMW 4 Series and while I love the sleek design and handling, I feel like it could use a bit more power. What are some ways I can increase the horsepower without compromising the performance or voiding the warranty?

One way to increase the horsepower of your BMW 4 Series is by adding a performance chip. This will optimize the engine's performance and can add up to 20 horsepower.

Another option is to upgrade to a high-flow air filter. This will allow more air to flow to the engine, resulting in a boost in horsepower.

Consider getting a performance exhaust system. It can improve the flow of exhaust gases, increasing horsepower and adding a more aggressive sound to your BMW.
