How can I increase the horsepower in my BMW M1?

I recently bought a BMW M1 and I am looking to increase its horsepower. What are some recommended modifications I can make to achieve a noticeable increase in power and acceleration?

One way to increase horsepower in your BMW M1 is by installing a performance air intake system. This will allow for improved air flow, resulting in better engine performance.

Another option is to upgrade your exhaust system to a performance one. This will help the engine breathe easier and can contribute to a significant horsepower boost.

If you want to take it a step further, you can also consider installing a turbo or supercharger kit. This will provide a substantial increase in horsepower, but it can be a more expensive and involved modification.
