Why don’t they use a doughnut air filter anymore?

Why they don’t use it anymore is that with a fuel injection system, the air filter is typically relocated to a place away from the throttle body, and has a different design and shape than the traditional doughnut-style ones. This different shape allows it withstand the engine vacuum much better, and it doesn’t need the mesh anymore.

Can dirt affect the air flow in the fuel injection system?

Your fuel injection system has a few sensors that measure the air in a few ways (temperature, airflow meter, etc) Dirt can cause errors in the readings and require replacement. Not cheap. Some fuel injection systems use a “hot wire” airflow meter. Dirt/bugs hitting the wire at high speed could possible break the wire or at least make it useless.
