How does an engine “suck” in air? Like during the intake stroke it goes down which creates a low pressure area and the air rushes in. But how does all that work? How does the piston going down allow air to be pulled in? LOL please explain it as simple TY!

Think of a syringe. As you increase the volume on the inside, more air will go into it through the opening.
In an engine, the opening is the intake valve. It opens and the piston begins to pull away, causing air to rush into it. Then the intake valve closes, fuel is added, and the piston compresses and ignites.
There are other methods too.
Turbochargers use the exhaust flow to spin a fan that actually sucks in and forces air into the intake. More air means more fuel and more power.
Superchargers are very similar, but instead of using exhaust gas, it uses a belt.
